Tyler Cowen explains why he supports the government of Evo Morales, with nine separate points. Since he is an unabashed free market advocate, it says something that he pokes through the ideology and sees a pragmatic government with broad support that has brought stability to a country that has been lacking it. This in particular should be heeded by those who label Morales as a leftist puppet and yearn for Goni or whomever.
If a Bolivian government is not strongly connected to the country’s indigenous population, that government cannot have a strong base. Yet it will still work hard to stay in power (#2), which will mean it will resort to oppressions and distortions, with high long-run costs. Bolivian history has seen an especially large number of coups and attempted coups, illustrating this weakness of the power base, which you can think of as the major problem in historical Bolivian public choice.
Bolivian elites and the U.S. government alike have pretty well ignored that common sense.
