Obama has to pay a huge bill that has come due. That's the extreme support he received in the election from the labor unions. Therefore protectionism (which has never worked) may well come to pass in his administration. Look, it's a well established fact that at least one of the Big Three (Chrysler, General Motors and Ford) has no chance of surving... no matter how much is pumped in and out of the remaining two (GM and Ford) GM has only about a 50/50 chance of survival. Why not let economics take its course, you say, and let them go bankrupt and reform?... Simply because the unions are owed to much of a debt for Obama's election.
I respond well to the charge of cynicism, by the way... But it woorked well with the airlines, with which I'm intimately knowledgable, and the surviving ones are much more able to prosper following the process...
If we here in the U.S. establish any form of protectionism, the results will be identical to the events leading to the Great Depression of the 1930's. Who said doing the same thing over and over and expecting different results is a definition of insanity?
