Well if that's what OP is saying they are wrong. Don't look at the market from the perspective of the one of the participants, look at it as a whole. And don't try to evaluate something like anti-trust in a marginal way, when the effects are so numerous. Better to take a more stateless / path-independent approach and just find the new equilibrium, for the first rough-cut analysis. From those perspectives, higher Gini coefficient clearly means lower median, etc. From your other comment it looks like you agree with my conclusions, at least.
