What is a dollar?

So Ben Bernanke says that the problem with America going back to the gold standard as a commodity to back paper dollars, is that there is not enough gold in the entire world to back the American dollar. So what does our govenment continue to do? Just keep on printing, and I guess we're still borrowing, if other countries will still lend us money. The only direction the value of the dollar continues to go is down. That is why gold and other precious metals continue to rise to record levels. Our government doesn't seem to be too concerned about the inevitable march toward hyper inflation. They give lip service to our debt and deficit problem, but continue to spend, spend, spend monopoly money. America has operated for so long on a false monetary system, now it's come back to bite us big time. Folks we are in deep doo doo! All I can say is educate yourself, budget like never before, find ways to sustain your family, and pray!
