Some people, looking at what hedge fund managers make and what security guards make, believe the disparity to be unjust. However, it is one thing to document economic inequality, it is another to show that those inequalities have negative consequences.

Over the past 50 years, the periods that have seen the strongest income growth at the top have also seen the biggest declines in poverty and increases in middle-class incomes. Countries with more inequality tend to have lower- and middle-income citizens who are richer than their counterparts in nations with less inequality. And while inequality has risen, most evidence suggests that economic mobility has been unchanged over recent generations.
