The best thing that can be said about the five "promise zones" announced by US President Obama as the War on Poverty turned 50 this week is that they probably won't do any harm. They might even do some tiny amount of good for people in the targeted areas: neighbourhoods in Los Angeles, Philadelphia, and San Antonio, and parts of southeastern Kentucky and the Choctaw Nation of Oklahoma. But they sure don't address the root causes of poverty, insofar as such things can be said to exist.
