There is no argument on THAT front. However, the "general affordability" of everything in general relative to income was MUCH better and continued through the 70's into the 80's when fiances got tougher and tougher for indificuals and families... in spite of inflation being a major concern of the 70s (remember Whip Inflation Now?).
For reference, I have a mere "music ed" degree, but with that, my first house cost approximately 2.5x my annual salary (wife never worked once we had kids and it was all on me). Life wasn't "easy", but it wasn't nearly as stressful as it is today. When I upsized my home 7 years later, my next house was about 3x my salary. Compared to what it costs our kids today, people with master's and doctoral degrees, BOTH spouses HAVE to work and the homes they purchased are 4-5x their COMBINED income. The same thing can be cited when purchasing cars back then. With a modest one-income salary, we got a new car every three years, though admittedly cars back then didn't last 10 years and went to the wrecker at 100,000 miles.
I dunno... Things today are complicated and IMO kind of a mess and really difficult to compare things from different eras because there are more facets involved pertaining to "affordability". JMO
