“This telephone will be the biggest seller not only in Venezuela but the world. Whoever doesn't have a Vergatario is nothing. ... It is science and technology at the service of the people not the elites ... the day will arrive when we manufacture phones for Cuba and Latin America.” (Google translation)
Two years ago Chavez pushed Verizon and the Mexicans out of CANTV, creating an international incident. U.S. folks swore the Venezuelans couldn't run a phone company, so it became a point of pride for Chavez to do well. Profits at CANTV and Mo are up, prices down, market share increasing, and Venezuela is one of the few countries in the world with major growth in landlines. History will tell us whether that's a side effect of the oil boom, smart policy, good management or a mirage. Authoritarian states can do well – China, Malaysia, Singapore – so the question of government form and economic growth is unanswered.
