I've lived in big cities like that and I can tell you its still pretty much the same thing. Even though I hate this word but I had been what some consider a pick up artist before I got married, although a quite successful one. My n-count is in the higher double digits and I've dated a a "Miss" beauty pageant winner from an eastern european country that competed in the Miss Universe.

There's endless science that supports why this happens though. In order to understand why this exists we have to go back in history. For every single man that reproduced, theres 10 other women that reproduced [1]. That means that a significant percent of the male population died without having any offspring, unlike the female population which could always find a partner. On the other hand, polyginy has always been practiced throughout the world universally pretty much everywhere in most cultures, especially by men of influence and power, unlike polyandry which is quite rare [2]

The theory goes that evolutionary speaking, women try to find the best mating partner (most well-off, most influencing, most powerful etc) in order to secure the best future for their offspring to grow up healthy, without any regard whether that man already has other offspring or partners. This is also supported by the fact that women 100% know that the offspring is in fact theirs since they gave birth to them, unlike men which have zero assurance that the kid is in fact theirs. And this is why for most of recorded history premarital sex for women in civilized societies was a big no no up until like the 1950s that started to change in the western world.

So dating apps create this perfect environment where choice is abundant, so men take their shot on everybody, and girls only choose the most handsomest, most well-off guys on there. Its similar to a big high school environment, where most of the popular pretty girls from all years and generations would date a dozen guys in the sports teams and just swap around every few months. In high school and college I was in a similar situation, and girls were in fact excited that I was so experienced and that I was seeing other girls at the same time.

On dating apps most men get somewhere like 0-4 matches a week and most women get somewhere like 100-1000. That’s a 25x difference best-case scenario and often it’s over 100x. Which is kind of insane considering there are about 50/50 men to women ratio in real life.

People say “the 20% top men get 80% of matches” but it’s worse than that. The 20% top men may get something reasonable like 3-4 matches a day, but your average women is getting something crazy like 1 match every 15 minutes.

Because a lot of men like to swipe right on nearly everyone and buy passes which get them unlimited swipes. And most women get extremely choosy and swipe right on only the super handsome nearly-perfect men, but you can’t even blame them when they have literally 1,000 matches.

So dating apps are a waste of time, much better to go out and talk to girls in real life and get yourself out of the synthetic environment apps like Tinder create. You'll have much easier time.
