I have never been in a union shop, with the execption of a summer job during college.
Sadly, there are no North American-made cars that come close to what I'd be interested in. Maybe the Ohio-build Civic, or the Geo Metro, but that is built in South Korea.
Showing my age again - remember in the early 90s when WalMart touted the "Made in the USA" products? I saw a documentary on PBS of American suppliers dependant on WalMart, who cut them out because foreign competition low bid them.
If WalMart tried harder to keep domestic choices, I'd feel a lot better about them.
