I can definitely relate to the concept of women who are beneath us being convinced they are above us.
I recently dated a single mom, 29, with stretch marks, an ex-fiancée who just dumped her, no job, and no money, and she thought she was WAY too good for me. Compare her to my previous girl, 22, equally pretty, no stretch marks, no ex-fiancée's, no kids, and she adored me. As women approach 30, they suddenly want guys who are 30 (who think these women are WAY too old for them).
There is a simple reason for women's inflated egos. The 80/20 rule. The top 80% of women sleep with the top 20% of men. This means the bottom 80% of men have to share the bottom 20% of women.
That means a guy who is a 10 has slept with the girl who is a 10, 9, 8 and 7. The guy who is a 9 has slept with the 6, 5, 4 and 3.
Hence, a girl who is a 7 thinks she's too good for a guy who is 9. Due to their shameless self-service, women feel entitled to be with the hottest guy who ever used them.
