The only basis upon which countries outside of India and China can compete globally and still maintain well-educated, highly-paid workforces, is on the basis of quality. However the GATT meetings in Brazil in the 1970s were about preventing quality issues becoming barriers to trade. In about 1992, Standards Australia developed an IS9000 type standard for OHS management systems, which they hoped to turn into an International Standard. The American industrial lobby groups through ANSI sent 40 delegates to the ISO conference, to stop that from happening. I have a shed full of Chinese tools, which are cheap but OK. My friend has Chinese NC controlled mill, which is excellent. To me that says, regardless of all difficulties, American corporations are manufacturing in China. That factor might be modifying Trump's thinking.
