Perhaps we need to complete the thought here: was it the unions or executives that decided to offshore manufacturing? If the counterargument that unions are to blame for offshoring by "artificially" increasing the cost of labor, and should have competed with Chinese labor on price and they got their just deserts: then why are executives now (successfully) lobbying for protectionism against Chinese manufacturers? Why can't capital handle the type of rugged capitalism they inflict on American workers? If chinese goods could be ported as easily and cheaply into America and American labor was ported to China, there'd be blood on the floor.

Neither. It was consumers, who prefer lower prices.
> why are executives now (successfully) lobbying for protectionism against Chinese manufacturers?
Because they were fools who thought they could offshore the factory work but not the management work.

This is literally what has already happened.
The actual solution is for the US to do something about high domestic costs, especially housing and medicine, which are the things keeping US workers from being globally competitive.
