> he had 5 children, a house in Daly City and 3 apartments across the street from Dolores park as well as a brand new home in Terra Linda How well would you need to be paid now in any career to support a family like that one while accumulating that wealth already early in life? Careers can evaporate just the same but what they leave behind is vastly different from 60 years ago.
How much wealth? Not really that much if you move to the middle of the country. You're thinking of San Francisco (well, Daly City) of the 2020's, which San Francisco absolutely was not in 1963. Nice place, sure, but still heavily working class, blue-collar and union. You could have 5 kids and a few apartments on a reliable, but not spectacular, income today in many cities (and suburbs of such) in the US.
How do you get this "reliable, but not spectacular" income in one of these places? What are these places?
