True. Venezuela should be one of the richest countries in the Americas. But -- as with all government-run enterprises -- the money that should have gone to exploration and basic maintenance of its equipment was instead siphoned off to bloat the government and buy votes.
If Venezuela was run efficiently, the Venezuelan middle class would be prosperous. The Communists do not want the middle-class to be prosperous. They want the middle class to be poor, with the underclass being paid to keep them down.
The Communists don't care if the country is poor, as long as the people who keep them in power are content.
