From what I understand Venezuela did pretty well under Chavez. It improved in alot of different areas.
And remember when Chavez offered heating oil assistance to american consumers who were having trouble paying their bills and the american companies told them to go freeze? That one caused a congressional hearing and forced US oil companies to finally offer assistance themselves.
All the hating on Chavez is ridiculous. While he wasn't perhaps the best leader in the hemisphere he did try to do some good. And the US's history of support for some of South Amereica's worst dictators, like Pinochet, justified his paranoia of DC IMO.
