I'm afraid that is mostly a myth. This source (https://www.longtermtrends.net/home-price-median-annual-inco...) shows that the home price to median household income multiple in 1950 was around 6, or about the same as now. It did fall quite dramatically during the late 1950's, going a bit under 5x by 1960 and nearing an all time low of just over 4x by the late 1990's.
This other source (https://archive.curbed.com/2018/4/10/17219786/buying-a-house...) shows that median household income in 1950 was $3,000 and the median "home value" was $7,400. Which is still 2.45x. By 2000, the multiple had declined to 2.17. I suspect the media home sale price was substantially higher.
Both sources show a surge in home prices during the housing bubble between 2000 and 2010.
Note, you also get a LOT more house now than you did in the 1950's. Much much larger, much higher quality, many more amenities, etc.
Lack of housing is by policy. By ensuring there are not enough houses ensures there is more demand than supply, which means higher housing prices, which means higher mortgages. The mortgage market is based on rising house prices. The banking industry is based on the mortgage industry. Low house prices, would mean a falling mortgage market, which means a banking crises. Given that the banking cartel has more influence on politicians than the populous, we have this current state of affairs.
Remember, in the 1950s a new build home would cost about 1 years salary. Now one year's salary might only buy a nice car. Building technology hasn't gotten worse, it's much better and cheaper. It's not the construction companies that need disrupting.
Edit: Also I should say that that was the state of affairs until just recently. This recent move by Blackrock and the like is the prelude to massive inflation. They are abandoning paper assets (cash, equities etc) and investing in hard assets like housing, farmland and commodities.
