The simplest way to get gas prices to drop at the pump is to suspend the federal tax on each and every gallon sold. We all know that the feds make way more money on gas than the oil companies do, just like the feds make more money off cigarettes than the tobacco companies do.
When it comes to greed, no one beats the feds.
California does.
The federal tax on gasoline is 18.4¢/gallon.
The state taxes add up to 51.3¢/gallon as of Oct 1st, 2012.
