To some significant degree, want and hardship create motivation. If we (vaguely specified) aren't distracted by that, we start noticing hardship and want elsewhere, e.g in our cushy lives. Life for our great-great-grandparents sucked much worse on absolute measures than for us. They didn't say "this sucks, let's die" and they also needed children to support them. Wealthier societies with a social safety net downplay the need for children in the family. I do understand that the future physical world looks worse than the present one. But hey the survivors are the ones who rule. You can make the choice to take a weakness mindset out of the gene pool and that's fine, there are too many people already.
