If profit margin by U.S. oil refiners has shot up 158% since 1999 (the year Exxon and Mobil merged). The consumer’s price has also gone up by a huge amount. Are you suggesting they not related?
I would like to see those numbers supported. I suspect you don't mean profit margin but actual dollars. Comparing to 1999 is cherry-picking the data to a year when oil companies we capping wells they couldn't afford to produce when oil was below $10 a barrel and many sold off assets just trying to stay alive.
Again, is keeping 10¢ on the dollar out of line?
