The RP space seems to constantly spread the notion that women "hit the wall" around their 30s, where their options begin to run dry and they can no longer compete in the dating market for the "Chads" they attracted in their 20s.

This to me seems like a big RP revenge fantasy.

In the same way men here complain that women only notice the top 20% of men, and base their perspectives of "all men" on this small %, men also do the same.

The average man in his 30s-40s is overweight, balding, and making around 40k a year. He's not attracting a harem of women with his looks or income. The average woman in her 30s-40s is also overweight and unattractive, but still has an easier time dating/finding relationships than men "in her league."

It is true that if you become a top 10-20% guy (based on a combination of confidence, looks, and income), you'll have a much easier time dating comparitively than in your 20s... but the same holds true for a "top 10-20% woman" in that same age bracket.

A woman in her 30s-40s who maintains her body, style, and employment with a kind personality on top of that will have no shortage of suitors for dates or relationships.

Last point, the "Chads" women can't get commitment from in their 30s are often the same "Chads" women can't get commitment from in their 20s+. There's (on average) no amount of looks, personality, etc that can convince a guy who has options and just wants to be a player to settle.

TLDR; This idea that most single women are crying every night with their 7 cats about how they can't find a man at 30 is, again, an RP revenge fantasy. It happens, sure. But tons of single women get their happiness from other places: be it friendships, family, work, hobbies, etc until they find a compatible partner.
