Some of usthem are just born so socially inept that there would never be a chance in any era, but I do think society has made it worse.
Men were sold a narrative. Go to college, get a good job, take halfway decent care of yourself, and the ladies will flock to you. When that didn't happen, is there any surprise that a lot of young men were confused and angry? And when they question it, they were told it still must be their fault somehow. It just HAS to be, because otherwise we'd have to admit that they were lied to.
We can't let them drop out of society either, because it turns out that horny young men are actually the backbone of the economy. So we use the carrot and stick. The carrot is that if they work just a LITTLE bit harder, if they just "put themselves out there" a LITTLE bit more, they'll finally find a lady. The stick is that, if they don't, we'll call them maladjusted anti-social mass murderers waiting to happen.
What are the perpetually maidenless SUPPOSED to think? I'm not saying that the full incel weirdos who want to chain women in their parents' basement are thinking in a healthy way, but how SHOULD they react? You can't win, you can't break even, you can't leave the game. What exactly did society expect would happen?
