US workers won't directly benefit.  Trump will court US CEO's to return manufacturing jobs to the US (one possible means of averting increased tariffs). 

Why did US corporations leave?  Higher costs of manufacturing.  

But, higher manufacturing costs will be passed on to US consumers (who are workers, not necessarily in the same manufacturing sector, but workers nonetheless.)  

So Henry Ford's ideal of "my workers can afford a Ford" may work.  But they'll be immense re-structuring of the US economy prior to that occurring.  

Can the US afford that in such global, economic conditions, where economic power is concentrated in a few individuals?
