"More people are waiting until their 30s to settle down" is a wildly different claim than "women are asking too much."
If the dating pool looks a lot different after that decade that also suggests that a lot of people are still "settling down" earlier, too.
So is the claim that "women are asking for too much, and too late in life" based in 30something men who fucked around in their 20s not having grown up as much as the women during that decade or something?
I met my wife in my 30s, on an app even, I also found I had lost patience for women who acted like they were in their early or mid 20s still.
