In EU countries many fees are regulated and have caps. For example, debit card interchange fee is max 0.2%. In the real world rich are getting richer and use their wealth to gain even more control too. But in a PoS system this is not a bug, but the core mechanic of the system. You can't even make a PoS system that is even slightly egalitarian, because then a "rich" wallet could be split into many "poor" sockpuppet ones and gain even more influence.
