Just tax a simple percentage on each barrel and pick a benchmark to calculate it on. AND THEN LEAVE IT ALONE. SET IT IN STONE. No windfall tax and just learn to live on the proceeds. Don't make it so it takes an army on their side and we got no one that can figure it out on our side. The devil is in the details so keep the details to a minimum. NEVER PLAY ANOTHER MANS GAME. They spend untold hours on coming up with ways to make money and our guys spend untold hours trying to get elected.
