The article comes off as slightly condescending; even as I'm 32 and just above the "Young men" threshold (Some of the thing mentioned, such as young women not looking for emotional attachment as much might be true, but what about >30 women?
My early 20s, online dating era romantic life was miserable; it made me feel completely worthless and that's a sentiment A LOT of young men get from those dating apps. I simply gave up, which was a good choice for a poor, stressed out and anxious engineering student.
However, around 28 and forward this drastically changed; and anyone above 30 can probably recall how the dynamic switches around this age group; men get more comfortable about themselves and women realizes that they're competing against people younger than them (which is a group growing every year). If family is a desire then that also add a sense of urgency
So suddenly (assuming you've put some work in) the dating (and sex) life becomes a balanced game.
This is ofc affected by other factors such as culture and demographics, which is closely tied to locations. But people have moved country and cities for all form of opportunities (including mating) so this is a way easier problem to solve, if one prioritizes it.
People already get married and have kids later, and have for a while. Only focusing on <30 males seems like a scope very useless to analyze the issue, if not from the negativa mental health consequences this have for young men
