Nicholas Fitz in Scientific American:
In a candid conversation with Frank Rich last fall, Chris Rock said, “Oh, people don’t even know. If poor people knew how rich rich people are, there would be riots in the streets.” The findings of three studies, published over the last several years inPerspectives on Psychological Science, suggest that Rock is right. We have no idea how unequal our society has become.
In their 2011 paper, Michael Norton andDan Ariely analyzed beliefs about wealth inequality. They asked more than 5,000 Americans to guess the percentage of wealth (i.e., savings, property, stocks, etc., minus debts) owned by each fifth of the population. Next, they asked people to construct their ideal distributions. Imagine a pizza of all the wealth in the United States. What percentage of that pizza belongs to the top 20% of Americans? How big of a slice does the bottom 40% have? In an ideal world, how much should they have?
