The Tokyo National Stadium design approved by a 2012 panel headed by architect Tadao Ando, is scrapped by prime minister Abe of Japan. The design was by the firm Hadid Architects in Britain. Public criticism over the cost of the project for the Tokyo Olympics led to its cancellation. The original project cost estimate was 130 billion yen, with the new cost almost double that of 252 billion yen. Surprisingly Tadao Ando says it was not the panel's job to figure out the cost and he did not have any idea what the cost would be when the design was selected. The debt problems in Greece began with the Athens Olympics. And it is widely thought that president Putin spent too much ($47 billion) on the 2014 Sochi Winter Olympics, especially now that Russia's economy is contracting and there is a need for stimulus spending on useful infrastructure.

Japan has accomplished a remarkable transformation of its workforce and its economy even as the working age population is declining. For years Japan was seen as a stagnant economy with a rapidly aging population. In recent years Japan has shown how a change in policy can work. Since 2012 working age population declined by 4.7 million, yet the number of people working increased by 4.4 million. The proportion of the population in the workforce rose sharply since 2012. To do this Japan turned to three underutilized parts of its workforce and population- the elderly, women and new immigrants. Japan has pursued an active policy of reviving the economy by bringing women into the workforce and breaking taboos on new immigrants. In 2004 Japan raised retirement age from 60 to 65, and then made it mandatory for companies to raise or abolish the retirement age, or introduce a system for re-employing workers who retire. This has changed Japan a lot with Japanese men working well into their 60's and 70's. In the west coast city of Kanagawa which now has a bullet train to Tokyo, out migration was a big problem that added to a declining workforce. The head of Ohara, a family owned company that makes desserts tried a novel method of advertising to seniors in apartment blocks and starting attracting seniors to fill worker shortages. It found that seniors came to work on time, performed even tedious tasks, and brought a great deal of experience. Since then the regional government has started programs to get more retirees and women into the workforce. The special programs teach small companies to adapt to the needs of retiree workers who can work in shorter shifts of few hours and do less physical jobs. Women need predictable hours to pickup children from school and shorter work weeks, for which the regional government program helps companies adapt by sending in specialists to guide the companies. As a result female participation in the workforce, for very long a big handicap is no longer so. Female participation has jumped to 63%, higher even than that in the OECD where the average is 62 years.  Japanese women had a M curve that meant they worked most in their 20's. less in the 30's with children, and more in the 50's. First the government tried to correct this with extended parental leave, increased childcare, and rewarding companies with good work-life balance. Then in 2009 the effort accelerated with employers required to offer 6 hour days if a worker asked for this. Under prime minister Abe's "womenomics" effort child care was significantly expanded- by 2015 Tokyo went from 28 to 38 spots open for every 100 two year olds. Alongside these efforts the Abe government tried to get companies to rethink their assumptions about quantity of work and overtime as productive effort. One could work shorter hours and be productive, and the old notions were seen as resulting in lower productivity. As fathers with parental leave took on more responsibility the changes transformed the attitudes for women at work. Most remarkable is the quiet change in immigration policy. The government allowed foreign construction workers to address shortages for work on the 2020 Olympics. It introduced a 3-5 year visas program for nursing care workers. Two new categories of visas will add 340,000 additional blue collar workers over next 5 years. The total foreign born workers in Japan doubled from 2012 to 2017 to 1.3 million. ...

Six cities have rejected the Olympics, with Calgary in Canada being the last one. The problem with hosting the Olympics is how much it costs. Cost overruns are common. 20141 Sochi WInter Olympics estimated budget was $10 billion, in the end it cost $51 billion. 

Brazil is the latest example of the problem. With huge needs in sanitation, epidemic prevention, infrastructure and public services, the country did badly by spending money on new soccer stadiums in the northeast which were not used after the World Cup soccer championship, and in the summer Olympics. 

Learning from these lessons voters in Calgary, Canada, rejected hosting  the Winter Olympics. Voters or local councils in Innsbruck, Austria, Rome, Italy, Bern, Switzerland, Hamburg, Germany, Oslo and Stockholm have rejected the idea of hosting the Olympics. Other problems are the environmental impact with deforestation to create Olympic sites.
