Exactly, which if the USA was smart they would do the same thing. Sell it cheap here and it would strengthen the economy because people would have money to spend again, instead of spending it all on living expenses.
Then if they want to affect the world price they could sell it cheaper than the current price which would force the other countries with oil to sell to lower thier price a bit.
As far as this new "idea" to help with the gas price, by temporarely cutting the federal tax on gas to lower the price for us will hurt us more than help us.
However the the tax hiatus would just cause a several billion dollar fund deficit in other areas such as roads and what not.
There really is no solution that the rich people in positions to make changes are going to change. As I said they are perfectly happy pulling out thier Visa Platinum encrusted diamond card and spending 230 dollars to fill the gas tank up on their hummer. Its a drop in the bucket to them.
