If the oil companies make the same profit per gallon, how do you explain the massive increase in their profits the last couple years?
We are using 50% more gasoline? I call BS.
The major oil companies don't make their money selling gasoline. In fact, they are running as fast as they can away from what little involvement they currently have in selling and even marketing/distributing gasoline at the retail level. Not worth the effort and they lack the entrepreneurial efficiency to excel on the street. The people actually selling gasoline (petroleum retailers/dealers) haven't made much on it for over a decade. The middle distributors (petroleum marketers) do somewhat better, but it's noting that great.
In the middle, refiners are doing OK now, but there is a lot of overhead and a long history of mediocre profits. The major integrated oil companies are not that big on refining either, given it comparatively low ROI.
The major integrated oil companies make their money facilitating the production (in many cases) and distribution of crude to meet world demand. Because there is much more demand in the past decade than ready production the price is high. Spikes occur based upon world politics and rumor (as with all markets) and likely to some artificial extent based upon speculation in the markets. As noted, $30 per bbl today comes from the devalued dollar. Every barrel produced is sold, and sold at market prices. Market price is very high and they are selling far more barrels = record profits, for now. The FTC has established no manipulation of the process, but... The oil producing countries can, ahve and do manipulate and are currently making a killing with their nationalized oil companies (basically controlling the oil rights and in many cases initial production). They are likely manipulating production as they long have, but the current oil shock in general it has been, at least initially, a reasonably honest demand driven crunch.
However, contrary to popular opinion, oil/refined products demand is not inelastic. A few percent swing in demand and all of the profits, and high prices as well, flush away as quickly as they rose and could easily stay there for a half decade or more -- as is histroically established. Again, not because the oil companies decide -- hey, lets tank our profits and screw our shareholders for 5 - 10 years for poops and giggles -- but because market conditions shift and that's the new reality.
