3,400,000,000 dollars. Picture it. You can't? Of course you can't...you're only human.
As scientists know, humans aren't very good at grasping the meaning of very large numbers. 3.4 billion is an abstraction too far for our weak little brains. I could tell you that the giveaway is worth nearly 2% of Venezuela's economy, almost three times the UN's guideline for developed countries' total foreign aid to poor countries. I could tell you it accounts for a staggering 15-20% of Cuba's GDP (depending on who's doing the counting). But those numbers are just as abstract: they fail to cause much of an emotional ripple.

Venezuela's oil giveaway to Fidel last year was worth over 16 MDCPs. About this much:
















Basically, we pay for their totalitarianism.
