In this audio BBC Witness History talks with Shuji Nakamura, the inventor of the LED lightbulb in 1992.  Nakamura shows the resilience and stubborn persistence against the odds that has given the world an extraordinary invention. The LED bulb does great things for climate change action because for example Califonria uses 35% of its electricity for lighting. The LED bulb cuts this in half and this means many coal fired power plants are not needed. In India, Indonesia and China this means lighting for about 3 billion people, with lighting for children studying in remote parts of India and China, and in Africa and Latin America. Nakamura took an unconventional route. He did his PhD in Japan not by going to school which is allowed in Japan, but by writing a paper on White LED development. He made a single minded focus on this goal. Nakamura says it made him angry that no one wanted to try new ideas and he persisted for years of research. At the time GaN research was done by less than one percent of researchers. Nakamura decided to try the path less trodden and by 1992 developed a blue light emitting LED bulb. Add phospor particles and blue becomes bright white LED. ...

"The privilege of United States citizenship is a priceless and profound gift." The 14th Amendment was a repudiation of infamous Dred Scott decision and stood up for rights of black people, at no time was it intended to bring mothers from Asia or Africa to the US to get automatic citizenship for a child. 255,000 mothers a year with no connections to the US arrive here for automatic bithright citizenship- US Supreme Court rules "no" June 27 2025, and objects to mothers filing the lawsuits for their children when the mother has no legal status. Justice Coney Barrett in a 6-3 decision says the district courts cannot make laws over the decisions of the executive branch for the whole country as they have tried to do till now. This means birthright citizenship executive branch decision cannot be overruled across the nation. Most of the lawsuits are filed in states favorable to this or that approach.  In a few months the Supreme Court will address the automatic birthright citizenship issue at its core. Can a mother come to the US just to get her child US citizenship coming on a visitor visa. Much of the nation sees this as belittling the value of US citizenship.  ...

A former U.S. Treasury Secretary reflects on the backlash against free trade in the 2016 U.S. presidential election, and calls for a shift towards putting more emphasis on how trade affects individual workers who are laid off or work part time. In the light of tax evasion following the Panama Papers Scandal he says the time has come for the emphasis to shift in trade policy and capital movements to tax havens, so that ordinary workers do not feel their interests are being ignored as elites frame policies for elites. He says the period when it was enough to defend global integration has been exhausted, and this is unlikely to succeed without a nation like the U.S. supporting it and global institutions. A new approach is needed, and this means shifting from international trade agreements to international harmonization agreements, where labor rights, environmental protection move to the top of the list, and enabling foreign producers becomes secondary. The whole overall emphasis must shift, says Summers, to creating hope and opportunity for middle class parents that their children can live better lives....

Italy's prime minister Berlusconi is changing the terms of the 45.15 billion euro austerity package after political protests. He has to weigh what is doable in the political context with demands from the European Central Bank, which is buying Italian bonds to prevent a surge in borrowing rates for Italy. The new measures as the old package unraveled are: an increase in the value added tax to 21% from 20%, increasing the retirement age for women in the private sector to 65 from 60 in 2014, two years earlier than expected, and a 3% tax on Italians earning above 300,000 euros annually. The street protesters in Bolgna, Milan Rome and other cities, protested that the earlier package unfairly put the burden on the working class. The cuts in local government spending in the earlier package would have impacted spending on items such as nurseries for children, drawing protests from teachers. The debate on an equitable sharing of the burden of reducing deficits is ocurring both in the U.S. and Europe, especially with high unemployment and lack of economic growth....

About 60% of the population in Guinea, Sierra Leone, and Liberia, countries worst affected by the Ebola virus are facing food shortages. Markets are closed in these countries reducing access to food. The virus is affecting West Africa in other ways. Ample food supplies with lower prices of corn, wheat and rice on world markets, as a result of supplies from Brazil, India and Thailand, is not reaching Africa because of restricted access because of Ebola. Clogged ports, and conflicts adding to this reduced access. In East Africa the FAO estimates 20 millon people face food shortages up from 15 million estimate earlier. The rise in value of the dollar in relation to African currencies is increasing prices of food. Food price inflation is leading to a situation where an household with many children in a relatively better off country like Uganda being able to afford only one meal a day. The result will be increase in malnutrition in Africa if solutions are not found to get access to large food supplies outside Africa with lower prices. ...

Lower oil prices in 2015 make it possible for president Joko Widodo of Indonesia to remove costly fuel subsidies in Jan. 2015. With the steep decline in oil prices this made it possible to lower fuel prices at the pump at the same time. The costly fuel subsidies cost Indonesia more than money spent on education and healthcare. This frees up money for other programs. In November the Widodo government fulfilled one of its election promises by sending out national "smart cards" to over 15 million poor Indonesian families, which gives them free health insurance and education related expenses for children for upto 12 years of school. Programs planned for infrastructure in 2015 include 13 new dams and long overdue upgrade to the north-south Trans Sumatra Highway. Critics point to the appointments, including for police chief and attorney general, that reflect the influence of Megawati Sukarnoputri, a former president and chairwoman of Mr. Joko's party, the Indonesian Democratic Party of Struggle, and of parties that supported Widodo. ...

He moves to Berlin from Frankfurt to be close to his two small children and family, who continued to live in Berlin after Asmussen moved to Frankurt ECB headquarters. Germany is likely to nominate Sabine Lautenschlager, member of the executive board of the Bundesbank, to Asmussen's position on the executive board of the ECB. The ECB Governing Council, including the six member executive board and the heads of 17 central banks, will now have the first female member.

Amazon has 15,000 employees in Seattle from global employees of about 97,000. New towers being built in downtown Seattle will bring 12,000 new workers to Seattle. The development is similiar to that of other companies such as Twitter which are developing urban spaces to attract young employees with children. This means the city has to bring public schools and create residential space in the city. The area Amazon is using was bought by Microsoft founder Paul Allen for development that never started and is from the city's gritty maritime past. Northeastern University based in Boston has started a remote campus near Amazon buildings. A park next to the Museum of History and Industry provides green space. And the Museum itself was renovated with a contribution from Amazon founder Bezos. Amazon's head of global estate and facilities, John Schoelter, says the renewal of the area was apparent as soon as Amazon began work in South Lake Union area. Instead of driving through this area people now mingle in urban spaces here. ...

The trial of Tian Wenhua, of a large dairy company in China, for failing to monitor the safety of baby milk powder, and covering up knowledge that dairy products contained impermissible amounts of melamine. The problem of milk powder tainted by addition of melamine chemical to watered down product to falsely raise protein count has been found to be widespread in China. About 300,000 children were sickened by the formula leading to 6 deaths. Tian and three other Sanlu executives are on trial. Tian says she knew about the contaminated milk powder in May 2008 but did not alert officials till August. By that time Sanlu had made 900 tons of the contaminated powder. Executives at Fonterra Group of New Zealand, which owns a large stake in Sanlu, came to know of the problem and insisted Sanlu make a recall. China's effort to bring western companies like Smithfield Foods to enter China's pork industry is part of the effort to build safety and credibility into food products sold in China.

Who will take up the difficult work in American childcare centers at $10-$15 per hour when retailers such as Amazon and Target are paying $20-$25 an hour during labor shortages in the US in 2021. As a result thousands of childcare centers in the US are closing and others are operating at a fourth or fifth part of their capacity. The result- less childcare and fewer women able to return to the workforce. Fewer men who can go back to work if caring for a child. This leads to further labor shortages. For a long time retailers like Amazon and Target were faulted for paying wages that made it difficult for workers to support their families. With the increase in inflation of about 5% in 2020-2021 it is even more difficult to pay for essential food and clothing. Another problem that America and Europe have lived through under different administrations in the last 2 decades is now getting even worse. Left to markets alone the whole system breaks down when one by one essential services such as healthcare, sanitation, childcare, transportation, cannot be provided. The US is facing an existential crisis not just in climate change but also in childcare, healthcare services. Both are caused by same source, a lack of emphasis on the right and essential national priorities. The causes go back to faulty capital allocation in America and Europe. $390 billion is allocated for childcare in Biden's plan in October, yet the Biden Families and Workers plan faces resistance. Gradually many of president Biden's programs for women including paid leave, child care and others are being shriveled into smaller and smaller amounts and the $3.9 trillion in spending for the workers and families plan is down now to $2 trillion.  The US and Europe face splits in society with one more urban and from the professional classes and the other more rural and in smaller urban communities and from the less educated classes each having different priorities. Only a clear resolution in the proper direction can bring relief for women, children and all segments of society, needed for a good society. ...

Some of the statements on the IMF Blog on Inclusive Growth raises the question-Does the IMF, the International Monetary Fund, as an American institution funding developing countries, and economists, grasp what people find troubling in 2022? One of the lessons of the economic crises for families and workers in the US and other countries is that wisdom, a grasp of the soul of a country and its people through the thinking of its founders, and common sense, should drive managing of economies, with a knowledge of how economies work- not economists. Some of that is already happening. America's central bank is headed by Jerome Powell who has wide experience and has knowledge of how the economy runs, is not an economist. He was chosen by president Trump and continues to have the confidence of president Biden for this very reason. Some of the statements on the IMF economic blog are- "Why jobs are plentiful and workers are scarce" Jan 2022 "In the US and UK recent labor market the puzzle, can be partly explained by mismatch, the pandemic's effect on women and older workers leaving the work force." The Reality Wages for teachers are depressed compared to workers in the financial and economics industries, in a frighteningly disproportionate way. When it comes to logistics, hospitality, leisure and restaurants industries workers were paid poorly for what is hard work and long days. In case the IMF economists, and economists at companies, missed this it was called the Great Resignation, people simply choosing to reject the conditions that were handed down to them by the financial industry and economists who built the economic structures of recent decades. Women leaving the workforce are faced with issues of mental health coping with added responsibilities of children at home for the two years, loss of income and widespread mental health problems. The word mental health may be beyond the grasp of economists and the financial industry, yet it is the one of the biggest problems for people. Another pernicious effect noted on the pages of the WSJ is that young white men are dropping out after school because they cannot afford college in alarming numbers. Leading to the kind of discontent for workers and families that president Biden is struggling to address. On IMF Blog- "IMF Podcasts: The Year in Review" Dec. 2021 "The past year has brought us new challenges even as the old ones persist. If anything, the ongoing pandemic has taught us to think differently abut tackling the challenges and questions when it comes to thinking about big issues such as climate change, gender equality, inflation and economic measurement." The Reality Climate change lumped in with economic measurement and inflation. The floods, fires, river and reservoir water levels affecting access to basic life supporting water, drought, all over the world are of a magnitude that is missed entirely.The response to a challenge of this type requires the kind of leadership that president Biden has provided for the world with his $360 billion climate change bill as just the first step of many, and  comprehensive policies covering all aspects of the climate crisis. ON IMF bog- "How Domestic Violence is a Threat to Economic Development." "Stopping violence against women is not only a moral imperative, new evidence shows it can help the economy." The Reality Domestic violence hurts children growing up in such households. It is not so much a moral imperative as it is bad for men, women and children. So many things are wrong about it and it is made worse in conditions of low wages and poor working conditions in poor neighborhoods lacking education. These neighborhoods are also affected by lack of healthcare and the opioid crisis and mental health issues. Not investing in education and healthcare in these communities is what is simply wrong, and which the founders of America as a nation, particularly Lincoln, would find appalling.   Relationship between Capital (the Financial Industry) and Labor (Workers and Families) On the basic issue of the relationship between capital and labor, the IMF and the financial industry, economists, and the economic structure they built in recent decades, have simply got it wrong. It violates both common sense and wisdom, and violates the spirit of the founders particularly Abraham Lincoln. This is what Abraham Lincoln had to say on Upward Mobility, the ease with which each generation can do better than the one before it, as critical in the fight to save the Union. This is from the Annual Message to Congress Dec. 3, 1861, at the start of the Civil War. That upward mobility has been lost in the US with ideas that "place capital on an equal if not above labor, in the structure of government," for the last three decades in the US after the early post war period of Truman and Eisenhower, Kennedy-Johnson.  And Lincoln says this about a hired laborer being fixed in that condition for life, or of future generations of that hired laborer facing disabilities and burdens, similar to the loss of upward mobility for the people today. "Now there is no such relation between capital and labor as assumed, nor is there any such thing as a free man being fixed for life in the condition of a hired laborer. Both these assumptions are false, and all inferences based on them are groundless." "Labor is prior to, and independent of capital. Capital is only the fruit of labor, and could never have existed, if labor had not first existed. Labor is the superior of capital, and deserves much the higher consideration. Capital has its rights, which are worthy of protection as any other rights." "Again: there is not, of necessity, any such thing as the free hired laborer being fixed to that condition for life. Many independent men everywhere in these states, a few years back in their lives, were hired laborers. The prudent penniless beginner in the world, labors for wages awhile, saves a surplus with which to buy tools or land for himself, then labors on his own account another while, and at length hires another new beginner to help him. This is the just, and generous, and prosperous system, which opens the way to all- gives hope to all, and consequent energy, and progress, and improvement of condition to all." Lincoln even offers this warning- No men living are more worthy to be trusted than those who toil up from poverty- none less inclined to take, or touch, aught which they have not honestly earned. Let them beware of surrendering a political power which they already possess, and which if surrendered, will surely be used to close the door of advancement against such as they, and to fix new disabilities and burdens upon them, till all of liberty shall be lost." US president Biden has these ideas in mind as he struggles with one piece of legislation after another to restore what once was, to open the door of advancement, to remove these disabilities and burdens that Lincoln speaks of, and in so doing restoring liberty.   ...

A World Bank 2008 Report concluded that Brazil's current state of education would lead to its falling behind other developing economies, and act as a constraint on growth. Brazil's 15 year old chidren came in 49th out of 56 countries on the reading exam for the Program for International Student Assessment, with more than half scoring in the test's bottom reading level in 2006, with scores in math and science worse than that. Of the 25 million workers who could join the work force in 2010, about 22% are not considered qualified for the labor market, according to a government report. The World Bank Report says Brazil stands to miss out on the "demographic window," in which increasing numbers of younger workers make the economy more productive, unless it addresses problems in education.

Al Maktoum is prime minister of Dubai. He points out some important facts about the Arab world. About half of the 300 million people in the Arab world are under the age of 25. Unemploment is very high among these 150 million Arab youth. About 50% of the jobless are youth, according to the prime minister. About 65 million of the Arabs are illiterate, and 10 million children under the age of 25 are not enrolled in any school. He points out that with so little education, the Arab youth are especially vulnerable to propaganda that creates extremism and is hostile to the west and the USA. One of his key points is that the Arab world is the most militarized place in the world, and spending on conflicts in the Middle East in the last 60 years is about $3 trillion. And in the last 15 years he says the spending on education which is 20% of what the world's 30 wealthiest countries spend, has dropped to 10% of that amount. And very little is being done to educate girls and give them opportunities. As a result of these convictions, Al Maktoum, who is also the ruler of Dubai and from the royal family, has committed about $3 billion to various initiatives to provide schooling to children, especially girls, and education for young people. This makes him one of the more enlightened leaders in the region pushing for new directions. This also reveals the critical weakness among the Arab peoples and why they tend to be so radicalized. Improvements in education and more opportunities for jobless youth, and creating a peaceful region -with the US and the EU countries committing to policies that lead to much diminished military sales to Mideast countries and reducing hostilities in the region -would do more to reduce anti-American sentiment in the region and improve US security than any other policy actions. As Iran, Pakistan and Afghanistan, and the Muslims of India share the same characteristics as the Arab peoples, and the same cultures, the same is true of this region, actually more so. Education has been even worse neglected in the South Asian Muslim region than among the Arabs. It is the key to peace, does more than troops to ensure the peace. The need is for more schools to be built and run in the region, for essential services like healthcare and development, and financing of job creating industries. ...

Gerard Baker in the WSJ points to issues of transgender, illegal migrants in US cities, and race in politics as issues on which the "correct" views were causing anxiety for the American public. Parental anxiety on transgender at school for their children, public anxiety on illegal migrants in American cities, and anxiety about race as a defining factor in political life. The illegal flow of fentanyl and loss of life in the US is a basic issue- how could the US as the largest advanced economy in the world become so feeble that it cannot stop illegal flows of fentanyl and human smuggling. Baker also says that he doubts that the new Department of Government Efficiency will work and eliminate waste, that he thinks imposing tariffs will depress domestic productivity and reduce living standards of the people. And that installing what he calls "oddballs" will work except to create chaos. On the issues of infrastructure, cost of  manufacturing revival in the US which were issues in 2016 and turned into the agenda of the Biden years little is said, and on cost of living nothing tangible about reversing the 20-30 percent of price increases in housing and groceries that have happened in the pandemic years 2019-2023. ...

Jonathan Zimmerman teaches education and history at the University of Pennsylvania. Here he looks at the origins of the term "people of color" and to what extent there are changes in America that relate to the relevance of the use of the term in American vocabulary. He says the "people of color" term in our vocabulary was based on the idea that America was a white supremacist society that would not give average people, disadvantaged people a fair chance for a better life, whether they be the 48 million black people, 62 million Spanish speaking people, or the 25 million Asian people. To a large extent as America moves into the middle of the 21st century most Americans see themselves as part of the creation of the Modern World, with science and technology at its core.  Even Spain which early in the 16th century settled this continent, for two centuries lost its place in the Modern World created in Northern Europe after the Renaissance, falling into poverty, then recovered its origins when it joined the modern world in the 1970's by joining the European Union. A science museum  financed with EU funds in the ancient city of Valencia, Spain, brings Spanish children in every day to know Spain's own achievements in science and the advancing world of technology. ...

Elite universities with a third foreign student enrollment displacing Americans, are facing US government funding cuts. This report shows these universities turning to pharmaceutical companies and big tech monopolies that have placed added burdens on cost of living of ordinary Americans, and mental health of children, on the ability for basic literacy by 4th grade. Somewhere the basic goal of the university to educate Americans is being lost. For no more than 5 to 7% of funding these universities are willing to turn to companies that have exacerbated the cost of living crisis or monopolistic behaviours in the Nation, particularly the pharmaceutical companies, showing alevel of misguidedness in management that fails to understand the real interests of ordinary Americans. In pursuing science alone at the expense of everything else and derelict of leadership where it is needed such as cost and value, this behaviour ignores the fact that the greatest dangers to public health come from cutting chemicals in food, in healthy food and exercise habits cultivated in schools, raising the consciousness for healthy living and healthy environments in the Nation. The schools of public health at the Nation's leading universities needed to take a better stand on the dangers of proliferation of  research into viruses, and to single out breakdowns when they happened that are seen by many to have led to the pandemic.  ...

This report in the WSJ looks at the war in Ukraine in July 2022 as seen from the Ukrainian side. Ukraine has 12 million people displaced or refugees, about a third of the population, particularly in the east. Most of the refugees are women and children. Cities in the east and the south face artillery attacks and airspace over Ukraine lacks the air defense systems that would help Ukrainians live lives not constantly under threat of bombs going off. In this situation and with the massive damage, there is also a breakdown of trust on both sides. Not just the leadership but 93% of the population is against negotiating a peace till the territories lost in the south and the east are regained, says this WSJ report. This report shows Zelensky describing his typical day, his yearning for peace, but serious fears after the failure of the 2014 peace agreements with Russia that Russia is simply negotiating agreements so that it can consolidate its control over territory till it launches another attack. This means that the war will go into a counter offensive phase in the south where Ukraine has its economic links on the Black Sea around the port of Odessa. Ukraine will want to recover the territories in the south so that its future on the Black Sea is restored to what it was before. The eastern part of Ukraine in the Donbas region is being integrated into Russia and Ukraine may seek to improve its position in that area around major cities that it controls and controlled till losses in June.  The lack of air defense systems over Ukrainian airspace that would protect civilians and people of Ukraine in the countryside and cities is what hurts Ukrainians the most. It is the reason why there are so many refugees and displaced people. The US and European countries have failed to provide the air defense systems that would have protected the civilian population and created the worst aspects of this war in the number of refugees having to flee their homes and seeing them destroyed. Years from now people may look back and say this is the worst aspect of this war apart from the claims of either side. As Lincoln said during the civil war in the US in his annual message of 1862 the land is there for ever, and this generation will pass away. The conflicts and tearing apart that this generation of Russians and Ukrainians have experienced, may not be the feelings of future generations.  ...
