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.
