What neither of those men covered.
Gasoline speculation. Which was illegal prior to 1990, but now controls almost 60% of that market.
So you have speculators driving up the cost of oil, as they have been since the dawn of the industry AND you have speculators further driving up the cost of gasoline.
In some states the gas speculator profit margin is in excess of 20 percent.
That is a 60 cents per gallon savings to consumers in those states if the government brought back the ban on speculators in the gasoline market.
