I actually think guys did better in high school and made better matches then.
Freedom = Chadfucking
See, in high school, everyone knows who is fucking who. It's hard for beta Stacey to fuck Chad without alpha Stacey finding out, and beta Stacey is less likely to fuck Chad if she realizes that Chad value alpha Stacey more, which is likely because everyone in high school is so few degrees removed from each other. You're part of the tribe and accountable to the tribe.
Once you get to college and beyond all the bitches are fucking Chad because they don't even, accept that they other girls exist. There's no fighting. They're all pretending they can be Chad's number 1, and the alpha Stacy isn't coming down on any challenger that appears with her posse.
Hell, a top 3 girl from the class below me was dating a 40th percentile dude in my class, and I know that, that same girl was dating a 6'0'' model faced, muscled 0.1%er wealth Chad in college.
