A common yardstick for measuring societal equality is the Gini coefficient, which runs from 0 (everyone has the same income) to 1 (one person has all the income).  Most countries range between 0.25 and 0.6.  The Economist shows that the Gini coefficient has gone up a lot in some rich countries since the 1980s.  And as poor countries are on average growing faster than rich ones, inequality in the world as a whole is falling.
