Oh, it still happens, EElisaveta, no doubt, I just think clever women are the ones to first notice that "settling" is not a good idea.
I know a woman who was with an idiot because she thought she couldn't get a better boyfriend. She now has a better boyfriend. The improvment is mainly in her realizing that she CAN do better, but still. With many women remaining single, there's some chance the most horribly misogynist assholes will have to stay single because even those women who feel they need a boyfriend can get a better one.
Or were you talking about my statement on spinsters? I was mainly talking about spinsters who ARE single, even though they would, theoretically, settle for any man.
The woman I mentioned above had no problems finding that stupid guy she was involved with first. He practically fell into her lap when she was a teenager.
A less superficially "pretty" woman might have to put a tad bit more effort into it, but I doubt involuntary singleness is a large-scale problem for women. (Not finding a GOOD man, is, yes, but finding any man at all ...)
