I don't think it's unfair to expect adults to be able to afford a 1 bedroom with no roommates
This isn’t to say the city can’t or shouldn’t be more affordable. But the idea that everybody gets their own 1BR at average US rental prices is not immediately compatible with the city’s housing stock (or troubling trends, like dedensification).

People were able to afford places, but being single for majority of adult life is semi-new trend. Especially in very dense cities.
