> People who would be considered wealthy by 1920's standards are considered poor today.
I did a double take when I read that sentence. Is this really true? The 1920s in the West (North America and Western Europe) were a golden age for income inequality. The rich were... well, crazy rich. Would they really be considered poor today?
That is a cheeky reply, but some light research tells me that the Rockefeller family borrowed huge sums of money to build that complex. Also, modern day technology billionaires worth 50B+ USD could easily build their own Hudson Yards -- the modern day equivalent of Rockefeller Center in New York City.
Typically these arguments boil down to how many high-tech items you can afford that were still crazy expensive back then, completely ignoring things like living space that actually matter much more to your quality of life.
It completely depends on what standard of living you want. People who would be considered wealthy by 1920's standards are considered poor today.
