I saw a part last week and it seemed biased against maduro. there were a few of the news articles cited during the show - ostensibly to show the nationalization of the industries failed and were corrupt. after reading the article (and a few other things), my only conclusion at this point is that the country is OK with some degree of corruption (kickbacks/bribes/theft), so when it occurs, it's tolerated for some time. however, it's not only the maduro party who engages in it. there are dozens of political parties in Venezuela.
viewing this in the context of their political climate (the vice segment starts with "back in the 1970s, oil made Venezuela one of the richest countries in the world, but the coming decades would see money siphoned off" , all I can wonder is - who was stealing the money from 1970-1990? currency controls were in place before Chavez, and their centralized currency system has been robbed twice. i'll need to finish re-watching the vice segment since I had to take a break from reading their citation from the economist.
