Even in the nicest apartment I ever had, I still had to listen to my upstairs neighbor scream and beat up his wife.

sounds like a sample size/bias problem to me. maybe you're just drawn to slums?

Ah the libertarian solution. "Just stop being poor"

lol, no--you just made an unsubstantiated (and stupid) claim that any apartment that isn't an NYC penthouse is a slum, and i countered that you can't use the limits of your own experience to reliably define what the world contains

As someone who has lived in NYC, yes. The vast majority of housing in NYC is slum quality at insane prices
