The point is that corporations are biased toward making money. If the way to make money is to talk about how corporations are evil or how capitalism sucks, then they will do that. It's a bit simplistic to assume that because major media organizations are large corporations, they are always biased in favor of corporations or capitalism.
Its proven that 60%+ of the ownership of newspapers and media outlets are conservatives.
