Obviously it isnt black/white, and lots of factors are involved. There's infant mortality, that business with the workforce, religion, and a host of other things.
In the USA, we expect that our kids will need to be educated in order to have a good future, since all the jobs that don't require education can and probably will be outsourced (or replaced by robots). We also have access to contraception and abortion, so if we don't want to have a kid, we can just not have one.
People here who have kids early:
a) never considered their kid's future. (universal dumb)
b) are religious, and were encouraged to have kids early, had the option of contraception removed, were never educated about contraception, couldnt get an abortion when they ****ed up and accidentally had a kid, whatever. (cultural dumb)
