The federal government of the USA should do everything in it's power, INCLUDING PROTECTIVE TARIFFS, to stop the offshoring of industry outside of the USA. Alas, it does not. It allows corporations to offshore industry to China and elsewhere and re-import duty free just to sidestep having to pay Americans. This is a travesty and will have profound, very bad consequences. It already has.
Adam Smith never envisioned multi national corporations closing factories in England( applies to any industrialized country) and moving production to the third world to exploit cheap labor and then re importing the same product back into England duty free! Smith would have been hung for even suggesting that. That is not Free Trade. That is screw the worker trade.
And we should restrict Chinese ownership of US companies to 49% or less, which is what they due to our companies over there.
