Things are expensive. Housing. School. Food. Young people these days need to do more with their dollar, and it's worth less than our parents' dollars were. Getting married young is whatever, it doesn't necessarily cost a lot, but having a kid does. The average cost of having a child is a quarter-million dollars over 18 years. I don't know about you, but I can't afford that kind of investment, and I'd assume someone who is under 20 probably can't, either. So having kids young is stupid, yes.
