Online dating gets blamed a lot but I can’t help but think it’s the major driver behind this.
People traditionally paired up within social class, then for the last century or so with less familial involvement it became more about “equality” where pairing up meant someone in your league, 6s got with 5/6/7 but wouldn’t get an 8+ and didn’t have to go to a 4-
It’s only the last 10-15 years that dynamic has gone away and every woman expects an 8+ regardless of where she ranks and that coincides entirely with online dating proliferating.
