Its very simple supply and demand. As you create more dollars people demand less of them. For every dollar the government borrows the Federal Reserve has to print a dollar to buy the bond. The supply of dollars is going through the roof, so the value of the dollar must fall.

Compared to what? The fact is that the other currencies are in even worse shape, except perhaps the yuan. Compared to gold, it has already fallen quite a bit.

The Fed buys every bond the Treasury issues? OMG! You're stupid!
