It's about *power*. Power to control the flow of oil from the Middle East for the rest of the century. The neocons arent concerned with the relatively piddling amount of money earned from war contracts. They are concerned about the loss of military domination of the world if the US economy is strangled by the loss of access to cheap energy from the Middle East. Money is simply a tool to achieve that objective. Because Cheney could have been massively richer, by an order of magnitude, if he had stayed as CEO of Halliburton. Instead, he gave up that position to work towards advancing the neocons' political objectives.
