Our healthcare system is broken and no one can afford a house.
Healthcare, maybe. Although, breaking down US live expectancy by demographic or even just by states and comparing with the corresponding European breakdown shows that most of the worse outcomes in the US are not due to healthcare.
I would be curious how much the productivity increase from people being less sick, and the increase in personal spending and investment would offset the profits of leaches like private insurance companies
A big part of this is more lower skill workers in construction. Controlled immigration would be a great start.
Every once in a while you hear about this, apartments where you build it mostly off-site in a factory and then assemble the blocks on-site, supposed to be somewhat cheaper and much faster (for the last stage anyway), but for some reason it seems to stay experimental.
The quality tends to be lower, the floorplans are very limited, and there isn't much of a price advantage vs building on site.
Like, you can expect to straight up own a house during your lifetime without inheriting it or striking it rich.
Affordability is far, far worse.
