Commerce, capitalism, etc. nothing works under extreme wealth inequality, prices just don't matter then. When someone has too much wealth compared to the others, it doens't even make sense to trade when the rest can only sway your wealth so little. So when arguing about inequality, we're actually arguing just how much inequality exactly the system can work with.
