I think it makes more sense to look at it through the lens of labor distribution. Money is abstract and cyclical and can be inflated and deflated by policy, which makes it complicated to draw conclusions about. But money is ultimately used to influence the distribution of labor, which we as a species have a finite capacity for, and which has concrete impacts.

As a person becomes wealthier, each marginal dollar is less likely to be used to support critical infrastructure like food distribution and more likely to support the construction of mega-yachts. And because the labor pool is finite and subject to competition, increasing the leverage of the mega-yacht industry can have a negative effect on other sectors' abilities to meet people's basic needs. This is why I hold income inequality to _generally_ be a negative thing under capitalism: not because of any moral judgment on rich people, but because a certain level of competitiveness among individuals in the labor market is a requirement for survival.

edit: whoops, everyone else already made this point while I was typing. Sorry for the pile-on.
