>The competition knob is but one knob among many. It's the one America happens to have at about an 8.5 (and one which I dislike greatly), but I don't think this problem is unique to capitalism.

Given the levels of consolidation we've seen over the past 30 years or so, I'd say that a lack of competition also contributes to unethical behavior. In fact, the consolidation pursued by many corporations is predicated on swallowing up even potential competitors in an effort to consolidate their dominant position.

I'd say that was unethical too.
