I know a lot of people who inherited some small place from a relative and they rent it out to supplement their income and aren't anywhere near upper middle class. What is you definition of upper middle class?

I don't believe "middle class" is anything but a psychological game.

You either have to sell your labour to someone else or you don't.

The concept of a "middle class" seems to just make half of the working class think they're better than the other half.
