That page says the average oil company makes 10 cents a gallon, and the federal govt gets 18.4 - 1.84 times. As far as "the arabs," see
http://www.eia.doe.gov/pub/oil_gas/...ons/company_level_imports/current/import.html for why that's not an accurate statement. First of all, we're our own biggest oil producer - about 44% of what we use. Second, Canada and Mexico are one and two, Venezuela four and Nigeria five on the list of the countries we import oil from. Saudi Arabia is three and Iraq is Six. So it's hardly all going to "the arabs." The 16.8 number you got right, at least on the surface. Drilling oil ain't cheap though, so it's hardly like that's pure profit.
Oh, and a couple asides. On that page the company complains about the windfall tax reducing discoveries. Could be true, but honestly we're going to find it and burn it sooner or later, so who really cares? There's no way this society is going to anything
but burn every drop of oil it can get its hands on, until it runs out or gets so expensive the system doesn't work anymore.
