We haven't had to make decisions solely based on survival and bloodline continuation for a long time. We're also capable of meta-cognition, so even if some realize that they may want children, they might reason that it's an infeasible idea.

Personally, I grew up in a below poverty line single parent home and would like to spend time and money for myself and my SO now that I'm doing OK financially.
