I think we've got a bit of time yet before the US dollar tanks, but if Obama fulfills his promise to spend a Trillion dollars next year, the money will have to be printed to pay for it as no other countries are liable to buy any more US treasury paper, and the hyperinflation will start. In 1929 Germany took 2 1/2 years to get to hyperinflation, the US has only been printing large amounts of money since September so it may happen in the next 12 months. Anyone remember the pictures of people taking a wheelbarrow load of German marks to the bakery to buy a loaf of bread.
