Tldr

But I read m2ms post, and it seems like a "rich white men rule the world" type post. You might want to add "going to war constantly" and encouraging terrorism because it lowers pop. Also, increasingly high rent costs that make it harder to afford children, and useless degrees that make for less attractive mates.

Anyway, if i got the general idea right, the biggest flaw I see with the argument is that it isn't working. Women in the workplace didn't decrease population. Gays do have biological children (especially lesbians). Trans have children. Birth control and abortion, while they do stop life, also encourage sex. The lives they prevent may not necessarily have occurred to begin with. Still, they often delay kids, not stop them entirely. The women I know all want kids (except for some high strung lawyer women), and many have had multiple kids even though they are not church goers. And perhaps most compelling, the growth in the US has continued to increase and doesn't seem like it's stopping.

So I can see this being some kind of population control plan, but if so, it's a bad one. I can't help but feel that of some scary people in a dark room wanted to do this, they would find a far more effective method than pinning their hopes on a cultural shift.
