Simping is not a symptom of anything women are doing. Guys who blame their loneliness on women who are "chasing chads" are willingly chasing girls who clearly don't want them.
Not all girls have access to all the men they want, and not all women want access to many men. There are plenty of girls who aren't out there chasing chads and would make great partners for these men. But these men also have unrealistic standards and only want that 10/10 stereotype. Instead of trying to meet girls who actually want relationships these lonely men are throwing their money at egirls who show off their buttholes on the internet. Who in their right mind thinks that's the ideal woman to cure your loneliness?
