As a Venezuelan, I think the difference is not the Natural Resources, or at least is not the main difference. In 2017, the shortages and economic crisis generated by 15 years of communist policies has pushed around 4 million people out, and then, the regime "elected" a Constitutional Assembly which has the power to create a new Constitution and to overrid any previously elected organism (as it was at the time the opo…

They were just much more committed to winning the propaganda war than a place like Venezuela is because their worldview was formed at the end of the Victorian era when travel and communication was much more easily restricted. Maduro's socialist worldview was formed much later, when the idea of preventing Venezuelans having access to capitalist ideas would have seemed much more ridiculous.
