I watched a piece on BBC last night about Venezuela and the state of the country. The doctors are paid in Bolivars, the local currency but the government allows commerce to use the $US as well. The exchange rate means that a doctor is paid $3 US a month. Now we have commented previously about how petrol in Venezuela retails for $0.01/litre (Global Petrol Prices), so that means a doctor can only buy the equivalent of 66 gallons a month. So despite the apparent cheap price, petrol of prohibitively priced even at $0.01/litre.
