The great divide between our beliefs, our ideals, and reality. An excerpt:
In their 2011 paper, Michael Norton and Dan 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?
The average American believes that the richest fifth own 59% of the wealth and that the bottom 40% own 9%. The reality is strikingly different. The top 20% of US households own more than 84% of the wealth, and the bottom 40% combine for a paltry 0.3%. The Walton family, for example, has more wealth than 42% of American families combined.
