Repairing the U.S. Social Safety Net by Martha Burt and Demetra Nightingale does an excellent job highlighting the current state of U.S. social safety net policy, as well as its origins. It also does a nice job highlighting that, despite complaints about how large it is, the U.S. social safety net is woefully inadequate when it comes to supporting the American people. The authors note that in comparison to other countries, U.S. social indicators (such a infant mortality rate, poverty rates, and housing needs) are much worse, in large part due to our weak social safety net.
The book is an approachable and engaging discussion of key issues of public policy and well worth a read.
