It's not up to the men though. This is something the people in very Tradcucked countries that promote the "strong men" fallacy have a hard time accepting. It's 100% up to the government because the government controls the laws they enforce on the men and women. If he goes home and tries to knock up his wife, what if she denies him sex? What if she gets pregnant than leaves him? Child support? What if she gets an abortion? Men have 0 control in society. The reason Russian men aren't having kids is because the women don't want kids. They want their careers. Or the men feel having kids would make their life significantly worse because the women use the laws to exploit the men. What good is having kids if you never see them and some single mother who fucks black Tyrones for fun and runs an onlyfans raises your kids while you're forced to slave away for her?

If you want kids, you must control the women to be what men want. Men generally want kids. Men can't have them while the women are out of control and the government promoted women out of control. That's how Muslims have kids. They control their women.
