You are probably accurate in this, though not in the White-Knight sense you likely mean it.

Throughout history the vast majority of women (really, both sexes) simply had to, in a word, *settle*. They had to take any offer of marriage from the best person who would make (or agree to) one because social pressure, economic necessity, and physical limitations did not allow a perpetual search for Mr/Miss Perfectly Right as opposed to Mr/Miss Right Here And Now. Sexual activity outside of a (reasonably) committed relationship was simply too risky in terms of unintended pregnancy, and without children and a long-term partner old age would be an even more miserable prospect. Birth control and abortion have largely eliminated the first pressure towards marriage and the modern welfare state put a big dent in the second (at least compared to the majority of history) as well as enabling many women to become Mothers while mated to The State. Throw the 'Have It All' mythology of feminism into the mix and you have a real toxic stew that is making both sexes miserable.
