"I find it odd that foreign auto companies come here, are unionized, and they make a good profit."
Who says they are unionized?? ...Toyoya, Nissan and the like finds ways to use non-union labor, to squeeze everthing from the unprotected worker.
It didn't work out so well in Canton, Mississippi, did it?
Can't keep up with all of the plants.
I see that the Canton plant makes the Titan, and the Armada, but they shipped the production of the Quest to China because they tailored that product for the Chinese market.
And your point is?
