Article Summary
Recent studies about wealth inequality and income inequality indicate that the
American public's estimates of the distribution of wealth and income are quite different
than actual data suggests. With respect to wealth, the top 20 percent of households hold
more than 84% and the bottom 40 percent hold less than 1%, yet the public's estimates
were 59% and 9%, respectively. In terms of income inequality, the public estimated that
the CEO-to-worker pay-ratio was 30-to-1, whereas data suggests the actual ratio is
354-to-1, up from 20-to-1 in the 1960s.
President Obama has referred to economic inequality as "the defining challenge of our
time," and although Americans seem to recognize that income and wealth gaps have
widened, only 5 percent indicate that this inequality is a problem that needs to be
addressed.
