It feels more like people [used to] have kids because they fucked and hadn't made the connection between that and having children. Them working at whatever you worked at was just necessary so you can help them grow, keep an eye on them, and pay for their upbringing.

Why on earth would you believe that? People have bred animals for millennia. You think they didn’t understand that sex was a required step?

I imagine people have understood that sex led to pregnancy since before Homo sapiens.

I think you underestimate human intelligence. People have made that connection for a very long time.

People didn't have options besides "not having sex" that worked very well.
