Kids cost a lot of money. Kids change your life and not always for the better. Women who have kids also sacrifice time away from their careers and end up with significantly less money in their 401k/ pension equivalent.
Going through my dad's fight with cancer and death recently significantly changed my view on the value of having kids. I shudder to think what it would have been like for him and my mom had my brother and I not been around. Yeah there's care facilities for people who don't have anybody, but there's no replacement for family for when you stop being able to take care of yourself.
