The root of this for me is pretty simple, and thankfully probably temporary.
Societal attitudes always lag a generation or two behind societal change.
Take women's liberation as an example. By the mid 20th century we hit the point where society and technology no longer contained material, physical or economic barriers to women participating equally. Contraception had come, Jobs were no longer overwhelmingly manual labour, households didn't take a full time worker to run, state education was standard and long etc. etc. Everything was in place for women to have an equal place. Yet did all men (and women) magically adjust their attitudes overnight to this new reality? No.. it took another half a century to get to where we are now (I would argue that a girl born today is no longer at a disadvantage to a boy born today).
The same adjustment is happening for men. Over the last few centuries slowly the following practical changes have happened:
- They are no longer likely to be depended upon to support their family, and can no longer rely on this as their only role or main purpose
- They are expected (rightly) to take on half the family responsibility
- Online dating disadvantages un-appealing men much more than traditional dating
- They achieve lower results in school, and end up less qualified than their female peers in every subject (math's and science grades were the last ones to cross over a little while ago)
- Up until 35 - they on average earn less than their female peers
- Jobs and education increasingly require sedentary/concentration/social skills that they struggle with
- They can't guarantee their wife will be forced to stay with them forever
- Many can't buy their own home or provide a house for their families
- Modern Video games are so addictive and amazing they hit their psychological needs better than real life
etc. etc.
I could keep going...
Now, I would argue that most of those are a GOOD thing and NEEDED to happen for a fair society and fair families...
But, as with any social change, you are currently experiencing the backlash of those who fail to adapt. The men who adapted are happy and not-sexist or resentful, but the men who failed? who couldn't adapt to the new ways of dating so are incels? Or who couldn't adapt to what a family man now is, and failed in their marriages? Or who failed to adapt to the modern job market and failed in their careers etc.
They are resentful, angry and desperate to blame anyone except themselves. Women, the older generations, immigrants, the rich, the poor, the politicians etc.
And - as I mentioned above, there are dozens of podcasts and platforms who, (while not the cause of this problem) will gladly tell those men what they want to hear.. for a price. adding fuel to the fire.
