How much more manipulation can be done with Gold?

Gold is under 750 and silver is approaching single digits and under 10.00. Oil is down to 100 a barrel and agriculture (DBA) is crashing. The truth is, after watching Money as Debt (available on google video and youtube) it is clear to see that the banks are going to fail. Look at Bear Stearns, Washington Mutual, Lehman Bros and Freddie and Fannie and more to come after that. Yet the USD keeps going on. This smells like major manipulation by the government and banks. It seems real that the stock market is going to crash, and now we have to wonder how much further commodities are going to crash and if they plan on bringing the price way down so they can buy it at dirt cheap prices.
