Howso? Those people cannot pervert the actual transaction, they will be slashed, and the money I believe goes to the node who proves them wrong, as incentive (don't quote me). It remains completely decentralized and effectively ungovernable, which I believe is the primary goal of cryptocurrency. I don't think it was ever meant to address the "rich get richer" effect.

Also, the practical upshot of the previous dynamic was that only people who could afford thousands of GPUs/ASICs/FPGAs could verify transactions, so it was basically the same effect with more steps.
