I would guess that people date mostly "inside" their social bubble (or with a similar social prestige). A broke bartender probably did not go to university etc.

I would guess that people date mostly "inside" their social bubble (or with a similar social prestige). A broke bartender probably did not go to university etc. and therefore the background is different to the accomplished women with an MBA. There should be studies about it, maybe there's a way to make the conversation more fact based? For example, all relationships formed at work will probably lead to similar backgrounds.
