Why Nations Fail

If you start in the city center of Nogales Santa Cruz and walk south for a while, at some point you see houses become much more run down, streets turn decrepit. You have crossed the Mexican border into Nogales, Sonora. Though the two cities are made of the same cloth and were once united, now there are sharp differences between the two. Those in the north are about three times as rich, have access to much better health care, stay in school much longer and of course take part in a much more democratic political process than their cousins in the south. The differences between the two halves of Nogales are a micro, tiny version of huge differences in prosperity and living standards we see around the world. Take Mexico as a whole, for example: it has less than one quarter of the GDP per capita of the United States. Take Peru; it has about one seventh of the GDP per capita of the United States. Or take Ethiopia, Haiti, Somalia or the Congo, each of has less than one thirtieth of the GDP per capita of the United States.
