Problem 7 - Economic Inequality Economists Norton and Ariely ran a survey to ask a panel of Americans (a random sample of 5,522 people) the same questions on their 'Ideal' and 'Estimated/Perceived' wealth distributions that you were asked in Homework #4. You can see their answers in the graph: Top 20% 2nd 20% Middle 20% 4th 20% Bottom 20% Actual Estimated Ideal 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Percent Wealth Owned Fig. 2. The actual United States wealth distribution plotted against the estimated and ideal distributions across all respondents. Because of their small percentage share of total wealth, both the "4th 20%" value (0.2%) and the "Bottom 20%" value (0.1%) are not visible in the "Actual" distribution.b) Look at the evolution of income and wealth inequality in this website httgs:[[realtimeineguaiiynrgz, and answer the following questions: i.
