Near Monument Valley, site of so many John Wayne westerns, the borders of Arizona, New Mexico, Utah, and Colorado come together at Four Corners. These adjoining states all share similar mountains and deserts. Yet the southern tier of Arizona and New Mexico displays practically Latin American levels of income inequality, while the northern tier of Utah and Colorado are almost Scandinavian in their economic egalitarianism.
The seldom-remarked links between economic equality (Liberals Like) and ethnic homogeneity (Liberals No Like) are made clear by the data displayed in a recent study (http://www.cbpp.org/1-18-00sfp.htm) by two left-of-center think tanks, the Economic Policy Institute and the Center on Budget and Policy Priorities. For all 50 states, they divided the average household income of the top 20% of the population to that of the bottom 20%. Utah is the most equal state in the union, with Colorado fifth. In contrast, Arizona and New Mexico are 48th and 49th.
