Well, isn't it already difficult for the not-rich to add to families? Add to that the uncertainty with income and future. Unless socialism is widely adopted, I am not sure humans can enjoy better lives especially with additional burden of kids. Hell, people can't afford homes now. I don't see a widely agreed upon or convincing positive ending. I already see (read about to be accurate) effects of AI on young graduates. I'd assume people hope for better ending, but would prepare for the worst.

When people say "people can't afford homes now" your referring to places like NY, MA, and CA where people can't afford homes because the local governments have made it basically impossible to build to match the demand in the areas? I.e. Massachusetts despite being one of the most desirable places to live ranks 50th in housing production per capita.

You're not sure humans can enjoy better lives in the future? Like you think things could only get worse?
