No, because wealth is not fairly distributed. The biggest predictor of wealth is being born rich. Looking at only the best case is not sufficient to call a criterion "fair."
Why do we need to judge people at all? If it is simply to feel superior, you can just make stuff up. "Look at that person with/without an iPhone while I don't have/have one."
Wealth certainly isn't the least-bad.
Also I haven't seen any evidence that encouraging people to judge others by one metric discourages them from judging people by other metrics.
Why do we have to judge on only one thing? Why can’t we judge different traits and characteristics based on different metrics? What does material wealth tell us about someone? What is it about them we are judging?
