So I learned it this way:
Upper Class - can live a luxurious life without working at all, and even have domestic employees etc.
Middle Class - can live comfortably but only if they work
Lower class - cannot live comfortably even if they work, and can very easily end up homeless (no social safety net)
The dude who taught me this was my Sociology of Work teacher over twenty years ago.

I’ve been using degoog.org for a few months and frankly the experience has been flawless. I’m thinking of self-hosting it.
