Capitalism is the driving force of almost everything that's wrong in America. [1]
I agree that bailing out a corporation is not very capitalist, but that is not the primary goal of corporate lobbying. I believe it is mostly about keeping their industry legal, unregulated, low-taxed, etc.
If you were a corporation, becoming a monopoly would be your wet dream. As a company becomes richer and more powerful, it gains more influence over politics. It's a feedback loop that gives them more and more power until they are monopoly. It's not the government that drives this, it's the corporations driving the government.
