So today what you have is what I call the middle 40 percent, the people who are not in the top 10 and who are not in the bottom 50, and what you can view as the wealth middle class that owns 20 to 30 percent of total wealth, national wealth, whereas they used to be poor, a century ago, when there was basically no wealth middle class.
今天您可以看到 中间40%的人， 就是除了前10% 和底层50%以外的人 您可以视之为财富中产阶级 占财富总量、国民财富的 20%-30%， 一个世纪前，他们更穷些， 那时基本上没有财富中产阶级。
