The drop in oil prices is hurting countries that rely on oil revenues. The greater their reliance, the greater their hurt. Venezuela gets 96% of its export income from oil. The economy 60% inflation. The government has instituted controls that are unsustainable. Even food, drugs, and banks are so inaccessible that wait lines take hours requiring some to pay others to stand in line for them. The longer oil prices are down, the more unstable the situation becomes.
