Unfortunately, it's a problem with our current dating system, because the girls aren't controlled as much by smarter parents. They date whoever gives them the gina tingles, and that happens to be the guys who can sleep with 10 women a month--so why would they settle down?
And then the majority of guys are single and get told "you're a nice guy, but I just consider you a friend" and such, until about 27, 28, when the girls realize, "Crap, I'm losing my looks and soon I won't be able to have kids, and the punk band player isn't going to marry me. Where's one of those boring nice guys I rejected when I was in my prime late teens/early twenties?"
Question is, will the boring nice guys keep accepting the tired carousal riders who are finally realizing the hot alphas won't commit, or will they decide, "Wait, you and your pals mocked and rejected me so many times before, why should I commit to you and help you get your dream of having kids and a husband who will support you *now*?"
