> "meeting girls at lunch" is a lot less of a benefit under modern expectations of workplace behavior.

I doubt human nature will change because or recent social mores. It will just adapt.

But over time, people tend to date people they meet regularly and get to bond with. I forget the percentages, but I remember reading a study saying that most marriages involve people who were classmates in high school, in college or were coworkers.

> But anyway why not join a social club for dating? That's where people go intentionally to socialize, so your "hit rate" will be much higher.

I'm not OP, but that's an additional effort and not always easy to do (for example your work hours could be longer, the social club might not be close by, etc, a myriad reasons).

See my previous part of the comment: a lot of people find their life partners in their vicinity, without going out of their way to look for them.
