Even North Korea is suffering from low birth rates it’s a wrap
I think this will actually inspire more wars. A society without equal power distribution will always run into the problem of what to do with its excess males.
The surplus males will always look at who is at the top and ask "why do I have to be down here and suffer whilst they can grow fat off the fruits of my labor and hoard the food and resources for themselves?"
A man who has a wife and children doesn't have time to ponder these things because he's too busy grinding to contribute to the wealth of the household and to manage crises in his own home. World wide there are literally millions of men who are expected to die alone and those men are an existential threat to you if you are someone with serious power.
To manage them you can placate them with porn, onlyfans and other internet distractions. But then when you lock down your internet because you don't want people seeing that shyt either, then you've just created men who will either give up and wait to die, or men who will be so angry that once they decide "I have nothing to live for, I'm crashing out" it can inspire thousands who feel the same way to do the same thing. Many of those men may even be in the military who is supposed to guard your interests if you're part of the ruling class. So now you'll have to worry about them turning their guns on YOU after they've mowed down enough of their own at your orders and what the people they've killed are saying is hitting too close to home to the soldiers that fired on them.
