Things with limited supply are becoming more unaffordable because the rich are much richer than they were before. So if housing is limited and is seen as an investment vehicle, it becomes unaffordable.
The same goes for health care. There is a limit supply of medical care. Some people can afford much more than others which compounds the issue.
Americans (and most of the collective West) can afford all things that are not in limited supply - food, clothing, gadgets, transportation, etc. This is amazing in the context of history.
The weirdest thing is that both health care and housing do not need to be limited supply. It's completely artifical. We make bad governing decisions that force it to be so. Our problems are not economic but social/organizational ones.
Relatedly, I was quite surprised when recently I realized that the median (adjusted for PPP) disposable income in America was the highest in the OECD (except Luxembourg):

This means that the average american really really is financially better off than anywhere else in the world. I'd say that their quality of life isn't - they die much earlier than the rest of OECD, for example. But they are definitely the richest. And not just the richest american but the average american.
