I did tech degrees, but its pretty amazing going to other parts of the campus where there are 2 or 3 or more women for every man in the building. Its also weird to see lots of well educated female friends finding it really hard to find someone to settle down with. Yeah they should probably lower their standards but honestly deep down most guys dont want an over educated achiever wife.
Men want to be wanted, and women generally don't want to be with a lower-status man than themselves.
What proportion of women tend to date men who earn less than them, are shorter than them, have a lesser degree than them? Not a very big one, and men know it, so they steer clear of those women.
Similarly, most men prefer to date women shorter than them, who earn less than them, etc. Why? I'd guess because most men like to feel like they're providers and protectors, and most women like to feel provided and protected for by their partner.
It means I won't be intimidated by my partner's credentials or success. "Over-educated" is not a thing.
If men were free to chase whatever professional growth they wanted and women just had to stuff it because they would be avoided by men if they were "over-qualified" according to you, then that's a dynamic I cannot wait to see completely obliterated. I'm not saying only one partner being a provider or sole breadwinner is a bad thing, but it absolutely does not need to be the only role possible. These men you and GP talk about need to figure out what else they can bring to the table in a relationship, because the ability to put food on the table is hardly the only "desirable" thing people see in a partner, and it doesn't seem like a great thing to tie your self-worth to.
