You misunderstood my response. Let me explain better: I'm not saying what matters is the relative amount of money you have in relation to your peers; it is about the relative claim you have on resources, power, respect, mental health, etc.
Money and those other things may be correlated, but focusing on those things emphasizes how much money is a proxy for them.
So for example, even if you earn 100k, but many/most people are earning 500k, it cause a huge power imbalance that enables them to easily make your life miserable on a whim. It also causes society to see you as a failure, causing mental/emotional distress that further pull you into a spiral of despair.
