Nowadays average girls sleep with the top x% guys from tinder instead of finding local average peers. They also out-earn their male peers and just a small percentage is willing to date down and settle with a guy earning less then them.
This brought kids to find refuge in videogames or the internet in general and be overall very lonely.
The media outrage towards typically male traits (think toxic masculinity) and a unmeritocratic culture (think everybody gets a prize, "positive" discrimination for "minorities" in college admissions and in the work force) is also incredibly damaging to guys who struggle more then ever to be successful.
The rise of porn, onlyfans and twitch (as it provides companionship) are clear symptoms that each passing generation is more and more lonely.
Loneliness will eventually breed creeps, incels, school shooters or people who are easily radicalised by terrorist organisations.
I think this is drastically overestimating the reach of Tinder. Some quick searching suggests that in 2020, 15% of adults between 18 and 29 used Tinder in some capacity. Meanwhile, Tinder's users are 80% male. Finally, less than a third of those users actually open the app more than once a week. Putting this all together, the number of female Tinder power-users might be about 2% of this particular age group, which is far too few to draw conclusions about the behavior of the average population.
That's a sad response—"I actually have to work at finding a partner, so I'll just not bother".
