How come gulf states dont sign long term contracts with China and sell crude for higher prices like Venzula is doing? Accepting U.S dollars that will surley go down in value over time for a finite resource is bad policy. Re-investing the money back in U.S banks like Citi is even a worst deal the should invest in there countries and infrastructure. Also waisting money on green energy research in which 1 in 100 projects will be cost effecient and make it to market is not the way to prosperity. They instead should invest in viable green energy that will generate power right away like wind turbines. Let someone else waist the money on research and jump on the "green" buzz word.
