"The wealth disparity between upper and middle income Americans has hit a record high, according to a new Pew Research Center Report. On average, today’s upper-income families are almost seven times wealthier than middle-income ones, compared to 3.4 times wealthier in 1984. When compared to lower income family wealth, upper income family wealth is 70 times larger.
It has come to the point where only the top 10 percent of Americans are seeing their wealth grow while the bottom 90 get less and less of the pie each year. The driving force of this wealth chasm are the top 0.1 percent, who have seen their share of the nation’s wealth grow the most over the past decades, from 7 percent in 1979 to 22 percent today. In fact, the top 0.1 percent are now worth more than the entire bottom 90 percent of the U.S. population, according to the report, which adjusts for the shrinking size of the American family so as to enable comparisons across time periods."
