Venezuela is so poorly managed they were losing money at $150/barrel of crude oil.
Last year, oil has been $30 to $50 per barrel. `nuff said. Its an issue of poor governance. Venezuela was heavily dependent on high-priced oil to keep their finances together, and it all collapsed as oil prices dropped.
Unfortunately, I don't know. I'm an outsider from the USA. So I don't want to get much deeper into the details and pretend I know a lot about Venezuela.
But clearly, they're doing something wrong down there. They are a very oil-rich and resource-rich nation. So they should have the money to do this correctly, even as Oil Prices have dropped.
