And to immediately reply to my own post:

I really really don’t want to raise kids, and this century is pretty much the first one where that’s actually an option.

I have a great husband, a suitable house, a good job (and so does he). But since we don’t want to spend two decades raising children, we chose not to have them. Because that’s an option. We don’t need children as a labor force for subsistence farming, we don’t get kids as a result of recreational sex and we don’t need children to provide for us in old age. That’s entirely new, none of those things were true a hundred years ago, and many still aren’t true in other parts of the world.

So yeah, even people who are super privileged like us, might still not have kids, because we think having kids sucks.
