> Really? In the 1970's in the US it was possible to own a house and support a family of 4 on a single income in the manufacturing sector. It was also possible to work your way through college and exit with a degree and no debt, in a job market which made that worth it.
Since the 1970s, physical house size has increased from around 1600 sq.ft to around 2600 sq.ft. At the same time, house occupants has dropped from about 3 to about 2.5 [0]. In addition to that, the building requirements and safety features have increased costs significantly per square foot.
Average house price in 1975 was around 42k [1]. That is a little over 200k in 2020 dollars [2]. Doing some math with 200k/1600 vs 380k/2600 gives $125/sq.ft and $146/sq.ft or roughly a 14% increase in relative cost. In 1975, median income was around 12k [3] while median income in 2018 was around 63k [4]. (EDIT: I'd note that I'm being generous as home prices dropped significantly this year and I went with the higher numbers)
SHOCK!!!!
An average house in 1975 is 16.5x the yearly income while an average house in 2020 is only 6x yearly income despite being 40% bigger and 15% less occupied while being safer to live in as well.
I'll give you college debt, but for all the wrong reasons. The government artificially incentivizes bad loans. They insist that kids CAN'T get that 380k house loan (even though the house is collateral), but also insist that kids CAN get that same 380k for a piece of (often useless) paper without any collateral backing. Get rid of the stupid laws and you'll watch that problem go away all by itself. Get rid of the pressure to have a degree to sweep floors and you'll watch college prices fall even faster.
