I think populations will crash, either gently through fewer kids, or violently through war and disease. That will likely throw us backwards technologically, maybe not.
Or, who knows, maybe the population will stabilize and we get everything going in the right direction, then an asteroid hits.
Well, mine are dead but my mom kicked me out at 17.
My first set of kids, I gave a little money towards college (they got scholarships and aid that paid most of it, we were quite poor) so they didn’t get student loans, and the younger ones I am letting live at home and feeding them and all as they are doing school locally but no cash, they have jobs.
As adults? No, not financially, but since they helped me with the younger ones I do have some indebtedness towards them. So sure, when they need something I try to help.
They all say they’d be happy to have a big ol family home with everyone in it, but if we ever do that I wouldn’t think of it as helping them at this point. Would be everyone helping each other.
