I don't think anyone objects to capitalism. And the US isn't capitalist..
The US doesn't have capitalism. The recent bank crisis demonstrated we have socialism for large corporations. We have socialism for the oil companies, we have socialism for the pharmaceuticals.
The only capitalists run the equivalent of lemonade stands.
Our space program is subsidized, funded by the government.
Capitalism is a buzz word used by folks propagandizing the masses. You can fool some of the people all of the time.
