I'm going to reply to you with some questions .

Do you think Toni Morrison , Malcolm X, Martin L. King, Charlie Chaplin ( I know he's british but he's career was in the USA), Michael Moore were capitalists?

Aren't they representatives nonetheless of American Culture?

Is the culture of a country merely and only defined by its economical system?

Isn't it pointing out to what is wrong and wanting it to be better a way of love?

Is capitalism a system only existent in USA society or is it wider spread?
