You are correct it is a long topic. Obviously many countries cannot afford current world market value for oil but I was thinking about countries (much like this one) that do subsidize fuel costs and the resultant lack of conscientious conservation (Most vehicles on the road in this country are anything but fuel efficient). I am sure that in most of these countries that it is only the well off that can afford to drive anyway, so maybe fuel subsidies should only be for mass transit and based on one's "address" for in-home subsidies. Again, most of these countries the wealthy congregate together.
