Again, the right either forgets or ignores that Chavez's programs were largely successful during his first decade in office, cutting unemployment and extreme poverty in half. Allied with Chavez, and a former left-wing president of Brazil, Lula da Silva, implemented the popular social welfare program Bolsa Familia which reduced poverty by almost 30 percent in his first term. Salvador Allende's policies in Chile were particularly helpful for Chile's poor. None of the subjugation you describe happened under any of these regimes, except the Augusto Pinochet regime we helped to install which resulted in the tortures and deaths of thousands of leftists.
Imagine you're Venezuela and your economy relies on oil, a nationalized industry in your country. Now imagine the price of oil drops. Worse yet, imagine the United States emplaces a sanction that cuts you off from oil trade with the U.S. (and effectively the world). Are you saying we can't blame capitalist nations at all for their interference and destabilization in South America? The Bush administration literally supported a coup to overthrow Chavez in 2002.
