research

Dan Ariely deals with irrationality . A study of wealth distribution attracted attention . The study, published together with Michael Norton in 2011, compared the views on wealth distribution with the real distribution: It compared the wealth distribution estimated by Americans , which they consider ideal, and the actual distribution of wealth. The result is shown in the following graphic:

From left to right in groups of 20% of the total population: wealthiest quintile to poorest quintile of the population. The two poorest quintiles are not visible in the actual distribution due to their low value (fourth quintile 0.2%, fifth quintile 0.1%).

The investigation showed that the ideal distribution of wealth differs significantly from the estimated distribution of wealth and from the actual distribution of wealth. It would therefore be considered ideal that the richest 20% own a little more than 30%. In fact, the richest 20% of Americans own 85% of the wealth. Accordingly, the poorest 40% (120 million Americans) should ideally own between 25% and 30%, rather than just the estimated 8% to 10%. In fact, the poorest 40% own only 0.3% of the wealth.
