There are always screams of "investigation" when oil prices get high. "Let's have a windfall tax" when oil companies make too much money. I don't hear any calls for investigation or refund when times are bad for oil companies. I just want to be "fair."
Actually, isn't it a great time for nations of the world to stock up on their strategic oil reserve? Buy when prices are low, sell some when prices are high. States can make a killing this way using taxpayer's money.
