All the transit equipment - particularly anything on rails - already comes from outside the US such a AnsaldoBreda S.p.A.(Now Japanese owned Hitachi Rail Italy) or Bombardier (Quebec). The LRT cars in my city come from a Spanish company. Also, much of the wind development in Pennsylvania is owned by Iberdrola SA - a Spansh Company. The hydropower turbines that were fitted to the the lock and dams on the Allegheny River near wher I live are built by Voith Hydro - a German company.
The US ALREADY does not build or design any new infrastructure technology aside from CO2-spewing airliners.
The base of the US economy is oil, bombs, investment scams and very little else.
At very least, for a start, European and Japanese car manufactures need to stop designing, building, and selling in the US all those US-market-only behemoth SUV car models, and start selling in the US the kind of small, efficient, 50 mpg+ cars that are everywhere in Europe and Japan.
