Deeper Understanding, I'm still trying to understand how higher standards means lower quality of women.

If women are saying no to 80% that is because the standard we see in men now do not match the 80% standard in women.

I will not go into details. But if you think about it women have become more self-sufficient than most men in terms of education, career and independence.

That is why most women would rather be alone that settle for 80%. But men never see themselves being alone, at least not as much as women do.
