But why should my standards be just better than most times in human history? That seems a low bar to me, most times in human history were miserable for the majority of people compared to the living standards I've become accustomed to.
To be clear, I don't feel there is any moral duty to continue my particular genes and the world population will continue to increase for the foreseeable regardless. If I were to have children I personally would feel guilty if they had it significantly harder than I have and I think the likelihood is that will be the case - it's really as simple as that.
If you could be born in America in 1925 and live until 2015, would you? Or would you decline because the standard of living dropped right away with a Great Depression followed by a world war?
I agree with you that if I knew, with certainty, that my children’s lives would be filled with nothing but suffering, I would make the same choice. But a fear of a theoretical drop in a standard of living, and which may not even impact an American over the next 100 years all that much, does not seem to me like it should reach that threshold, and I suspect it is starting to for others because of the media playing into their anxieties. There are people living that lived through the holocaust and are still happy to have lived and, over their lifetime, have had fulfilled and happy lives. I suspect your children could likewise carve out a happy life, even if their standard of living is somewhat reduced.
I agree you have no moral duty to have kids, and if you don’t want them, don’t have them. But if you want them, but are not having them because you find that to be cruel to your unborn kids, I question whether that is really a rational choice.
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.

Weirdly, the dominance of renting in Switzerland doesn't stop the Swiss having children. So this is really very much a media induced anxiety disorder of some sort. It's not rational to decide whether or not to have children based on whether you can get a mortgage.

As you can see, Swiss single family house prices were stable since 2016. It's a different lifestyle, there's a lot of apartment living with shared gardens for example, but it can be done.
