The report (pdf) "Building a Better America - One Wealth Quintile At A Time" by Dan Ariely of Duke University and Michael I. Norton of Harvard Business School (hat tip to Paul Kedrosky), shows that across ideological, economic and gender groups, Americans thought the richest 20 percent of our society controlled about 59 percent of the wealth, while the real number is closer to 84 percent.
More interesting than that, the report says, is that the respondents (a randomly selected 5,522-person sample, reflecting the country's ideological, economic and gender demographics, surveyed in December 2005) believed the top 20 percent should own only 32 percent of the wealth. Respondents with incomes over $100,000 per year had similar answers to those making less than $50,000. (The report has helpful, multi-colored charts.) The respondents were presented with unlabeled pie charts representing the wealth distributions of the U.S., where the richest 20 percent controlled about 84 percent of wealth, and Sweden, where the top 20 percent only controlled 36 percent of wealth. Without knowing which country they were picking, 92 percent of respondents said they'd rather live in a country with Sweden's wealth distribution.
As the new Forbes billionaires list, released Wednesday, testifies, the richest Americans are getting richer, even as the country as a whole gets poorer. After 2005 income inequality continued to balloon."
