I think you phrase the grandparent's comment much better than he did. That is much more clear. Appreciated.
But on housing, there's a major issue you're not considering. This [1] is a list of US city populations in 1950. This [2] is the list for 1960. So we're looking at the sweet spot of the housing boom and a period where the population also dramatically grew increasing by about 30 million (~20%) in those 10 years. Now you might notice something funny. Nearly every major city shrank in size!
The housing boom did not involve building up (rather literally as is the desire of some people today) in desirable areas so everybody could affordably live there. Instead people sacrificed some comfort and moved outside of cities and started building houses in uninhabited areas outside of the cities. Houses were cheap because people were developing in areas where there was nothing and that nobody wanted before. In turn this movement away from city centers helped keep those prices within the city reasonable, as it had a depressing effect on demand.
The reason prices are so high today is because of simple market dynamics. People are less willing to live in less desirable areas. This is driving the prices in desirable areas into crazy land. There is still immense cheap housing available outside of these areas. Some cities are so hungry for new citizens that they're literally even giving away land on the condition that you put or build a house on it.
