The US needs good manufacturing jobs for the jobs and income that it brings into communities, and also because of the tax revenues from the companies making products in America that provide the basis for local governments to provide good public services in healthcare, education, and transportation. To say comparitive advantage that helped first Japanese and now Chinese manufacturers is real and how society gains is to deny some basic facts that are self evident from observation that contradict textbook ideas in economics. Comparitive Advantage is a textbook economics concept that says countries are proficient in what they make best and should specialize in that product. But it is a static concept that exists only in textbooks. If Japan in 1960, China in 1980 and India in 2000 were each presented with this idea they would have turned down the idea of making steel and remained makers of lower end products such as footwear and textiles. If Japan in 1980, China in 2000, and India in 2020 were each presented with this idea they would have turned down the idea of making semiconductors and remained makers of lower end products such as steel. A senior vice president of US Steel in the late 1960's even told this writer a graduate student at Northwestern in Chicago- as the US can make steel better than India or China let us keep making it for you. He and much of the business faculty at Northwestern also could not understand in 1970 why Airbus was being setup to compete with Boeing who by the concept of comparitive advantage should have had the whole market to itself for commercial aircraft . By this kind of thinking Airbus would not exist today because it did not have the lowest cost or the manufacturing technologies Boeing had through its vast manufacturing operation. America would be still the only one making aircraft in 2023 if textbook concepts ruled the day. By indirect methods such as hidden preferential arrangements, provision of inputs such as land, capital and labor, tax relief, the costs can be represented in a way that shows it is cheaper to manufacture overseas. The lack of a level playing field is what president Biden is correcting by doing what first Japan, then South Korea, then China and now India are doing since the 1960's. By 1974 in four years after its founding in 1970 Airbus came up with its first model the A-300 using advanced technologies. America will regain its leadership in the cost and manufacturing of many products through Biden policy and the efforts of American companies by 2030, and do this in a transformative way that will benefit the world as a whole. It is an enormous error to say the US does not need good manufacturing jobs, that local governments do not need the tax revenues from manufacturing plants to build services for communities where manufacturing workers live, and the US does not need the manufacturing experience curve that leads to reduced costs. It is this loss of the manufacturing experience curve that is the most vital aspect for understanding the need for the US government to compete effectively with the governments of Asian countries to keep manufacturing healthy and strong at home. Economics experts ignorant of how important this science and engineering principle is fail to grasp this. Related to this is the idea of a virtuous cycle in manufacturing- whoever braves the hard years of moving up the learning and experience curve gets rewarded because once that country has mastered that skill it gets better an better as the technology advances- making it harder and harder to prevent a new monopoly in manufacturing by the country (Japan, China or Taiwan) that had the highest costs and the least advantage ten or 20 years earlier but just persevered through it all with the government's help to gain cost competitiveness. This part does not make it into the economics textbooks which are mostly theory and much of it outdated by the time they are written. Observation is the best teacher and guide as it is in science, to guide policy and action. Obsessive attachment to theory that ignores observation becomes the enemy of progress. Comparitive advantage is one concept that needs to be retired even from the textbooks. Overseas manufacturing then is a piece of the overall picture that fits into what is good for the US. Macroeconomic principles determine microeconomic outcomes as opposed to microeconomic principles with companies out on their own being forced to compete without a level playing field, or handing out technology for special status in a recipient country as some do putting the US at a macroeconomic disadvantage. This is also healthy for the recipient country overseas, as recrimination with loss of manufacturing jobs in the US inevitably leads to the kind of recrimination that does not serve either country well as in the case of China today, and worse still can lead to conflict, even war. After the egregious situation of loss of manufacturing communities across the US leading to destabilizing the social fabric, it is hard to see such thinking prevail about the US not needing manufacturing as a vital part of its social fabric and industrial strength. China, it can be said, would have developed, and developed well over the past two decades without overconcentration of US and EU manufacturing in China. Without aggravating the problems of climate change and contamination of air, land and water, and destabilizing the social fabric in the US hurting workers and communities across the US, if macroeconomic policy was made to manage this process in the US government without it being left entirely to individual companies to decide. Instead China faces today a difficult situation through events such as destabilizing the social fabric in the US (the Trump tariffs), advanced economies in G-7 resistance to sharing of technologies, the damage to its environment from microeconomic locally determined policy at individual companies, and the global effects of climate change from climate unsustainable levels of growth since 2000. ...
