They're not the people the post is talking about. It's the trust fund babies who just get everything for free, are given super well paying jobs because of their parents, and just never have to struggle.
Not their fault, just sucks to be on the other end of it
I just see two classes. The working class and the owner class. People who own entire large businesses without having to work at them or manage them? That's rich. The owners.
Anybody who has to work to live is by definition working class, though some working class people get paid very well and can lead decadent lives.
I might be caught saying they are well-off, doing well, are rewarded generously for their work, can afford more freedoms than most. They aren't rich though. Their continued labor makes their life possible.
