Of course. Thats the simple answer and obvious one. The quickest way to cheapen the gas would be to remove the Federal tax on it. But if ya really want to drop the price of oil, bring down the Dow to circa 6500.
Unlike Europe, our our state and federal taxes on gasoline are not very high, and amount to about $0.50/gal.
The best way to drop the price of oil is to raise the supply of it, and strengthen the dollar.
Problem is, you cannot pay back a $14 trillion national debt with a stronger dollar.
Remember Sarah's "drill, baby drill!" mantra? That was because during the campaign gas prices were about where they are now. Prior to Zero's election, and prior to the huge skid in the Dow, which forced investors to liquidate their commodities assets to cover their equities losses.
