People like to find ways to feel superior to others regardless of how much money they have. Money is just one of the easiest and most transversal ways.

But feeling like you have better opinions or thought deeper about subjects than others or that you know "how it really is", or that you're a better driver or whatever are other common ways. Whatever you feel like you are good at, or have a lot of, you will be tempted to feel superior about.

Fighting these thoughts is virtuous in my opinion. Pretending that only X type of people do it (rich or whatever) is not virtuous in my opinion.
