> If you grew up with $50M+ and lived a luxurious life, but lost it all, would you not have children over worries they may not have the same standard of living that you did?

I'd agree there's nuance to this. For your cherry picked scenario, no, that wouldn't affect my decision. I can accept a single person having a reduction in living standards. However, when most of Western society (I'm British, not American) is struggling to attain housing at a rate similar to the generation before, when the middle classes as a whole aren't able to become as financially secure as the generation before then it is enough to give me pause.

So ignoring any climate worries I already think things will be much harder. When you add on that it's estimated that billions will be without sufficient water in a few decades it's not hard to imagine that there will be significant problems of which I have very little confidence that we will be able to handle well as a species.

Perhaps I'm overly pessimistic. But as I say, this isn't the only factor we've taken into account, it's more a tertiary concern.
