I don't accept your premise. People who want kids have kids. This is obvious as I am pretty sure poorer people have more kids than wealthier people. I have never heard anyone say "I really want kids but I can't afford them" - I hear people say generically "oh kids are expensive" but I've never heard of anyone use that for their own decision. 60% of women aged 35 or younger have kids. That doesn't sound like a "luxury". And I doubt that these are the strictly richest 60% of women...
