Two Liberal Research Groups的意思|示意

两个自由派研究团体 The Center on Budget and Policy Priorities and the Economic Policy Institute, two liberal research groups, put out a state-by-state breakdown of Census Bureau data, which found nine states (led by New York) in which the richest 20 percent of households now earn at least 11 times the income of the poorest 20 percent. This indicated a much sharper disparity between the top and bottom than existed two decades ago.
