I didn't demonstrate a lie. If anything my post and your post pretty much confirms that the biggest threat to the U.S. auto industry isn't foreign competition ... it's the United Auto Workers.
Go back and look at what you posted again. "Union contract clauses" are the issue? The UAW sold its members out by negotiating away their jobs.
The cost of labor can be arbitraged inside the USA. But that requires a closed domestic market. The auto assembly plants were not the biggest part of the economy of Baltimore anyway. It’s a red herring. Those plants could have been bought by a foreign auto maker, but our government is corrupt and could have engineered that transition. Instead the entire city was thrown under the bus.
Those factories could have been sold to foreign makers but there was no motivation to do so. Just shutter them and throw all the workers out on the street. So now they, and their descendants, riot and burn CVSs.
