Oh, and I keep in my garage, not in commodity markets, to reach them more quickly. If U.S. Economy collapses, we're all screwed. Too much of the world economy is based in the United States for it to collapse, and if it did, would have much of the rest of the world with it. Other countries would do everything possible to halt the collapse, putting at risk too. It is like the Titanic, once the U.S. falls, the shock wave will suck for other economies in our step. There will be no safe store of value, except perhaps gold, and nobody will real money left to buy. Think of the Weimar Republic in Germany after the First World War, workers were paid twice a day and took your money around in wheelbarrows to buy a loaf of bread. And early in the century Germany was one of the economic titans in the world. The prospect of the American region economy is too horrible to contemplate the world, and everyone has a vested interest in keeping us going. The U.S. economy not going anywhere, and if you think, I would get more extreme measures that you propose, such as buying a farm in a remote area of the country and become a survivor.
