Two of the world's most influential thinkers reflect on the value of equality and debate what citizens and governments should do to narrow the gaps that separate us. Ranging across economics, philosophy, history, and current affairs, Thomas Piketty and Michael Sandel consider how far we have come in achieving greater equality. At the same time, they confront head-on the extreme divides that remain in wealth, income, power, and status nationally and globally. In this compelling dialogue, two of the world's most influential thinkers reflect on the value of equality and debate what citizens and governments should do to narrow the gaps that separate us. Ranging across economics, philosophy, history, and current affairs, Thomas Piketty and Michael Sandel consider how far we have come in achieving greater equality. At the same time, they confront head-on the extreme divides that remain in wealth, income, power, and status nationally and globally. What can be done at a time of deep political instability and environmental crisis? Piketty and Sandel agree on much: more inclusive investment in health and education, higher progressive taxation, curbing the political power of the rich and the overreach of markets. But how far and how fast can we push? Should we prioritize material or social change? What are the prospects for any change at all with nationalist forces resurgent? How should the left relate to values like patriotism and local solidarity where they collide with the challenges of mass migration and global climate change?To see Piketty and Sandel grapple with these and other problems is to glimpse new possibilities for change and justice but also the stubborn truth that progress towards greater equality never comes quickly or without deep social conflict and political struggle.
