I don't think anyone could a write a less accurate depiction of John Kenneth Galbraith's writings if one were trying. He did not argue against competition. He argued that modern industries tended to anticompetitive behaviors and that they could not be trusted to preserve free, competitive markets. He was right. Proof is in the behavior of the auto dealers.

I understand Galbraith is a Libertarian boogeyman and Adam Smith is viewed as the opposite, but they share a heck of a lot in common. It's sad to see such easily refuted ignorance elevated to the top of HN comments threads.
