Women wants only alpha males, period.
Almost all men are not alpha male, but instinct says "screw it, try anyway" with varying degrees of intensity (
depending on the education of the male can be from a polite "hello" to a rude "hi delicious").
Nowadays, if a non-alpha male approach a woman, she considers the approach as an act of aggression, regardless of what the male say ("hello" or "hi delicious"). Only a alpha male gets a friendly response.
Result: The educated males give up, and women end knowing only rudes because only rudes insist regardless of the response of women.
