This is indeed shocking.
The average home price in 1970 was about 23,000. The average in 2021 is 408,000.
GDP per capita in 1970 was $5234, in 2021 was $66,144.
So maybe not that shocking. The ratio of home price to average earnings per capita went from about 4.4 to 6.2.
And you have to admit that houses are much nicer now. you be the judge.
