Capitalism doesn't mean that everybody is running around for themselves. If its opponents seriously thought about that accusation for a moment, they'd realize that it is completely inconsistent with also talking about large corporations being abusive... indeed, large corporations existing at all. Capitalism allows you to freely set up your own organizations within its top-level free matrix, so if you find a problem space where near dictatorial "collectism" is the answer, you're free to choose that. (Fast food springs to mind.) That's in contrast to many ideologies which really do insist they are the right answer for every scale. Making that accusation of capitalism is generally a form of projection of the biases of the accuser, since it works exactly the opposite. (And the answer to many of the putative abuses of the system is for people to band together and form things like insurance corporations and credit unions and such.)
