Back in the day when Americans were well off they could afford $300 (same as $6000 today) plane tickets. We had a massive middle middle class with one worker families. Middle class today is at least $200,000, $3,850/week, is what you can afford for a months rent or mortgage.
Maybe the happy good times and prosperity ’45 to ’75 after WW II were an accident. But that era is my datum line. Base or reference point. A brand new 1950 Chevy was $1,000. The decent quality 1960s cars were in the $3,000s. Times 20? $60,000 is about right.
And those old 1950s cars were high quality body on frame construction, and high quality steels, still in service in Cuba, and SOOOO simple to fix. Gee, didn’t westerners get tossed out of Cuba too? LOL.
