this is precisely the entitlement I was hinting at - I was raised in an apartment - lots of my friends have been raised in apartments - I do live in an appartment (*1984) and we have many neighboors with children in our apartment building.
It is absolutely possible and also very humane indeed also to raise children in an apartment.
> But: apartments also aren't available! They're just as appealing to the downsizing boomer.
And this is just expressing the sad state of the US. The reason why there aren't enough apartments is not b/c of the babyboomers (also not b/c of migrants and Mexicans) - it's b/c your government fails to build them (I'm from Germany). Now you are stuck with a market in favor of people renting out own flats.

Not build at all - just live in an apartment or not move to super-hot-spot areas like LA or NY. If you can afford to build a house you can afford a car and you have to commute.
