Americans vastly underestimate the degree of wealth inequality in America, and we believe that the distribution should be far more equitable than it actually is, according to a new study.

Or, as the study's authors put it: "All demographic groups -- even those not usually associated with wealth redistribution such as Republicans and the wealthy -- desired a more equal distribution of wealth than the status quo."

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.
