Unregulated capitalism, I believe, can lead to its evil. Because it seems unregulated capitalism inevitably will produce several big businesses that stay completely out of each other's way to maximize their profits. It used to be that the general thinking was that profits were driven down by several businesses competing for the same market. Over the past few decades businesses instead go to other waters to maximize their profits while keeping a semblance of competition that doesn't pass benefits down to the consumer. The Japanese car industry did this to good effect for a good while, and some of the bigger businesses in the U.S. including HMO providers seem to be in the same basket.
