Breeding of humans only adds to global warming and futher threatens the other living species on this planet (and yes there is a big sarcasm tag on that one).
Jokes aside, if you can't afford kids - as you are relying on minimum wages jobs - they you should wait.
I understand the idea of waiting. When I was younger (and the eonomy was better) I remember friends had set the bar so high for what they were waiting for (they were “risk-averse”, and practically wanted their houses paid off before they would have kids). I also know people who waited too long, and when they were ready their bodies weren’t (a very sad thing). I wouldn’t suggest a course of action for anyone in particular on the question; I just think the consequences of either path can’t be ignored.
