摘要：The United States has a much more unequal distribution of
income than most developed nations.
1
Even though it has one
of the highest standards of living on average, as measured
by its gross domestic product per capita, the more unequal
income distribution translates into comparatively high rates
of both relative poverty (50 percent of median disposable
income) and absolute poverty (the offcial U.S. poverty
thresholds).

Some analysts suggest that high inequality and
poverty in any year are of little public policy concern, if there
are also high rates of mobility.
