There are policies that would simultaneously reduce inequality, heal some of the divides in our societies, and strengthen our economies. Then, I turn to the main focus of this conference – the environment – and explore its relationship to inequality. This paper takes a global perspective with a special focus on the United States, simply because America has achieved the distinction of becoming the country with the highest level of income inequality among the advanced countries. As others have followed America’s lead, they too have suffered increasing inequality. I.
