>they are uncomfortable with the fact they they are rich.The issue you're overlooking is that many $200k earners truly don't believe they are rich. It's not that they "secretly" think they're wealthy upper class and just want to lie to you.
It's not unusual for an employee earning $200k as salary from FAANG to feel like it's a middle class living. However, if that same person earns $200k/year purely as capital gains interest income from US Treasury Bills and therefore never has to work at a job for the rest of his life, that's the magic threshold to feel "rich". I.e. "FU money" means "rich".
(Yes, you can certainly disagree with those boundaries but I'm just trying to explain how people think.)
It's the necessity of working at a job that makes them feel like they are in the "middle class". It doesn't matter if it's a white-collar office job instead of a blue-collar factory gig. They can't be "uncomfortable with being rich" if they don't think they're rich in the first place.
I don't see how we can have productive discussions on social progress if we poison the well by slapping labels on $200k workers that they themselves don't actually believe.
