I remember once reading a RP description of "The typical woman's lifespan", which included something like "Adored by your teachers at 6, asked to prom by the quaterback at 17, railed by the entire football team at 20, angry bitter cat lady by 30" (and some steps in between).

This is a sentiment I have often seen on TRP that women who are attractive and popular in their youth will end up either alone or seriously settling when her youth is gone. However, I have never known any popular woman who ended up alone (other than by choice) or with an unattractive beta.

It seems to me like red pillers will look at the single woman dating pool at 20 and then again at 30 and compare the two groups, and when the latter group is less attractive and more desperate than the former, they assume that the 30s group are basically the same women as the 20s group, just 10 jaded years later. However, my experience is that the women who are most visible to men in the 20s group (the pretty and popular ones) have been married or LTR'd off long before they reach 30 and are therefore never part of the "single at 30" group.

The women I know who are single and desperate at 30 were never really pretty or popular. They were also single at 20 but were probably not noticed back then, because they were outshined by more desirable women. Now at 30 they are the only ones left in the group and do thus get noticed more. Single women at 30 seem a lot less attractive than the single women at 20, but that can be in part contributed to the fact that most women, who are still left in the dating pool at 30, were undesirable in the first place, also when they were in their prime.

In fact, not only have most of the pretty and popular cheerleader types been wifed up long before they hit the wall, if they are to get divorced they are rarely back on the dating marked for long (if at all) before she has the commitment of a new high value man. I have seen my mother's former cheerleader friends get divorced in their mid-40's and none of them were single a year after.

TL;DR: An attractive, popular woman will were seldomly end up a lonely cat lady, and most lonely cat ladies were always undesirable and lonely, even in their prime. The 30s dating pool is a lot less attractive than the 20s dating pool, because only undesirable women are left. Most truly desirable women never really hit the 30s and over dating pool, because they get locked down early and are taken again as soon as they become single.
