There is a debate about increasing inequality in the United States, other rich countries and also developing countries over the last 45 years or so. One person who have made a significant contribution to that debate is Thomas Piketty of France, in his recent book “Capital in the 21st Century.

is a discussion of Piketty’s book. Here is another article on the gap between the rich and everyone else over the last 30 years https://www.cbpp.org/research/income-gaps-between-very-rich-and-everyone-else-more-than-tripled-in-last-three-decades-new

This data is agreed by most economists to be robust, but there is a wide range of responses about what to do about it if anything, ranging from Piketty’s proposal for a global redistribution of wealth via a wealth tax to encouraging the creation of more small businesses, to simply allowing the free enterprise system to continue to function as it is. Discuss inequality and what if anything you consider would be an appropriate approach to mitigate it. Include data to support your reasoning.
