"As far as I am aware, the US does not have that problem"
Not true, we don't have a replacement population. This means all of your welfare programs and retirement programs will not have enough people in the younger generation to pay into them and support them.
"I hate the pretense that baby making for normies is anything other than creating workers for the ruler class."
Where did you pick this view up? Yes people have to work to survive. What do you think society would look like if you just did away with all the modern conveniences and the "ruling class". Do you just assume you'd be able to sit around doing nothing or pursue your "creative goals"??? No, you'd be gathering firewood and hunting all day, hoping you don't die of starvation or freeze to death.
This is such a silly naive stance. I hear it all the time and it sounds so childish. I assume it's some Marxist trope young people pick up from college sociology class and think they sound smart. What you want is a class of plebs doing the manual labor for you so you don't have to do be a "worker". Someone has to do the shit work, just not an elitist like you right?
My suggestion to you is to find an actual purpose and stop stewing in your hateful anti-humanist outlook. Having kids can be that purpose, but you could actually just go out and do something to be helpful to other humans too.
