Exxon and GM

In this post and this one I asked why Exxon didn't just bail out GM by giving each and every employee and every member of their family a brand new top of the line fully loaded SUV. After thinking about it I now know the answer:

1) Americans are still going to drive the same number of cars the same number of miles, so from the perspective of Exxon, what difference would it make?

2) They know GM is going to tank no matter what so why waste the money?

3) They are confident that Uncle Sam will do it anyway.

Take your pick, though I like each and every one.
