STEM / research jobs and certain niche fields like "high finance" and corporate law. Basically all the things that require a huge investment of time and money to be qualified for... except the education system should make it easier / cheaper for Americans to obtain those credentials versus their counterparts abroad.

Americans should be inventing the machines to replace workers abroad, not competing to be a Foxconn factory worker... This country's biggest competitor is probably Germany, and definitely not China.
