I'm curious: Do you have a postgraduate degree, and if yes, would you be willing to data someone with "only" a BSc?
Let's say that someone has a PhD from a top university, for them to date someone without a BSc involves a greater gap than if someone with a mediocre BSc/BA from a community college dates an electrician.

Here I disagree pretty strongly. An undergraduate will not provide the kind of class someone with multiple generations of doctors, lawyers, professors or "old money" tend to be instilled with during their childhood. Of course, those kids will almost always end up in college (if they're healthy).
In my experience, those from working class families tend fake their sophistication (often overcompensating) at least well into the 30s to compensate, if their education takes them into such circles.
In my experience, people who never went to college just have a very different outlook on life. There's a very good reason the political polarization in America today has a large component of being aligned along educational attainment.
