Because Big Labor and Big Business are in cahoots.
Big Labor is one of the main factors driving up labor costs -- along with government regulations and taxes.
this law will make it *cheaper* for US manufacturers to export their products.
No, it won't. It will raise costs. There will be retaliation and it will hurt America's economy and the world's. It will drive prices up and employment down.
Big Labor? What?????? 90% of the USA’s manufacturing work force is not in a union. 90%.
We are looking at the same thing from two different angles.
If big unions and business are in cahoots, what does it benefit the unions to offshore US jobs? The unions have been bitterly complaining about NAFTA, GATT, the TPP, etc., which have all be strongly backed by business.
Add to this that the big unions have had their teeth kicked in recently, as state after state creates right to work laws.
Granted, government regulation has become obscene, and that does markedly drive up costs, but president Trump is working hard to slash such regulations and make them harder to pass.
As far as exports go, how could exporting more goods possibly raise prices here? It would be self defeating for foreign countries to both subsidize their own businesses for export to the US *and* to have tariffs on US imports, which would cost them a fortune while hurting their importers.
Within the US, however, the increase in production by our exporters will provide lots of new jobs for Americans, and since foreign countries have limits to how much of our exports they can afford, the increased production in the US will cause prices of these things to fall.
