Alternative title: approximately half of workers can't afford an apartment that costs more than average. If anyone is more knowledgeable than me wrt economics and supply and demand feel free to correct my intuition here: As long as there's a distinction between "luxury", "average", and "barebones" apartments, it seems unlikely that we'll ever reach a point where everyone (or even, say, 90% of people) can afford a better-than-median apartment. If the number of people who can afford a nicer than average one becomes significantly greater than the supply of above average apartments, some luxury apartments will just increase prices until they hit a more profitable equilibrium.
