This New York Times book review points to a new book about income inequality in the U.S. and how it is shaping up to threaten our democratic institutions.
On the theme of inequality, a global perspective on the problem is reviewed here, with my review of The Bottom Billion. The phrase refers to the poorest billion people in the world, and the book is written by a World Bank official with wide-ranging expertise in the area.
Also of interest: the One Campaign to get the U.S. and other developed nations to devote 1% of GDP to world-wide efforts to combat poverty. It's unlikely to get much traction with Pres. Trump in charge, but I thought I'd link to it anyway.
