I've been hearing this since I was 10 years old. Yet, somehow, those men keep hitting on women 10 or more years younger.

And it is kind of hypocritical that you praise them for focusing on their career, hobbies, and personal growth while critizicing women for doing the same instead of focusing on dating those men.

Sure, marriage rates are declinig, birth rates are declining, but the ones who complain about that are the men and women like you, not the women who are literally chosing to opt out of that. Moder women won't claim to want your "high value men", they are rejecting them. They want other kind of men who treat them with respect, as equals and that allows them freedom and growth. A real partner, not a master. They don't care that much about marriage ans children because that is no longer their goal in life. You come from the wrong premise that marriage and children are the priority, but that is not true for many women.
