Capitalism is about one thing and one only, profit. Of itself, that's not a bad thing. Capitalism is not about efficient production, innovation, research, best use of scarce resources or free markets and competition.
That is not to say that those things don't happen in a capitalist society because they obviously do. But they happen only when they lead to increased profit and they only happen when profit cannot be maintained by another method like, say, cutting labor.
Business thugs decry regulation and the costs, but thanks to the EPA, to name one regulator, America's lakes, rivers and streams don't catch fire anymore. Corporations, particularly large multinational ones, have shown they are unwilling to police themselves and are quite happy to have the government nanny state clean up after them.
The same right-wing ideologues who want to cut benefits to poor people and label such as "takers' and "lazy" are perfectly fine with BP, Monsanto and thousands of other giant companies slopping at the government trough.
