It doesn't require superior intellect to understand that each child you produce will cost you about a quarter of a million dollars to raise. I'm of average intelligence I guess, but I'm well aware that I don't have that kind of scratch, or the time to do it properly. It's simple math, kids.
This nonsense about "haves" and "have-nots" is going to be a problem for you one day. I'm not saying it's fair, but life is not fair. If you don't understand that yet, your parents and your teachers have failed you.
