"So far so good. But the problem is, as in many dynamical systems, there are some delayed effects of such dynamics. ...Here are some numbers on the relative distribution of wealth in the American population. You have good data from 1983 to 2019... when we look at the percentage of households with [inflation adjusted in 1995 US dollars] net worth exceeding... Millionaires, roughly 10% of the population (7% now) increased from 3% to 7% but then growth in... classes such as decamillionaires was even more remarkable... more than fivefold, sixfold increase in the proportion of households that have 10 million dollars wealth, or more."
