So the question is - would the American economy be better off if GM imports all of its cars from China?
You need to get angry at a different villian, such as Congress my man. The envirowacko regulations, high taxation, and litigatious atmosphere is responsible for Wal-Mart (and other companies) moving manufacturing operations overseas.
Do you have any idea how many American jobs Wal-Mart has created directly and indirectly? When new Supercenters are built, another dozen or so other businesses spring up next to Wal-Mart. The sales tax revenues that hypocrites in state government who bash Wal-Mart over their "sponging" off of public health services but will pocket all the sales tax receipts that Wal-Mart generates.

GM makes awful cars, period. They suck beyond belief. Only Chrysler rivals them for poor quality. Nobody but GM is responsible for their impending demise.
Hey GM! Your cars suck! If you don't do something about it right away, you will be gone.
