What you've hit on is that even the ugliest woman still has some small amount of attractiveness whereas guys can go negative (0..10 vs -5..5). Not a single one of them lives up to their innate potential unless it's like in wartime or something.

Even the ugly ones have too much attractive privilege to suffer living in their car for years, getting heckled constantly, while they develop timing and other skills. But they at least try for a few weeks.
