> The net effect of this longer history is that renters today spend much more of their incomes on rent than they did in previous generations. The median renter household in 1960 spent less than a fifth of their income on rent. By 2022, housing costs consumed 31 percent of the median renter’s income. And in inflation-adjusted terms, the median rent is up 75 percent over these six decades while the median renter income has risen by just under 15 percent.
Even when I was a kid in the 1980s I didn't know a single person whose household had multiple bathrooms, a dishwasher, or air conditioning. Not a single one.
Part of the reason why standards have increased is because incomes have increased.
