This is definitely not true. As recently as the 50s the cost of a 2/2 house was about 14% of a single median personal income per month. [1] In contemporary times median personal income is about $45k, so that'd be about $525 per month. And they paid lower taxes as well. In contemporary times people pay dramatically more for housing without getting much of anything more in return. People often claim overall housing size has increased which is true, but lot sizes have slightly decreased. So all that means is in the 1950s you also had a much bigger yard instead of walk-in closets or whatever.
