> You could be making $10M a year, but if you feel like you need to make $20M, then you will feel poorer than someone making $100,000 who only feels like they need to make $50,000.

Yeah, but there is still very material difference between these two people. The difference is not just the feeling in the moment. It is difference in "if I get sick, how much healthcare I can pay" or "if I get into legal trouble, can I afford justice or layer" ... and either of those situations will change their feelings quickly.
