Maybe in the short-run. But I believe that - especially now that the illusions that we're in an endless boom economy and that the U.S. is a true democracy following the wishes of its people have started to pop (see this and this) - within the next decade, America will break up, like the Soviet Union.
Note 1: One precipitating factor in the break up of the U.S. may be the bankruptcy of the states. California, Connecticut, Florida, Hawaii, Illinois, Massachusetts, Michigan, Nevada, New Jersey, Ohio and Wisconsin are all in really big trouble, and on the verge of defaulting. The rest of the states won't be that far behind as the financial crisis intensifies. If the federal government isn't helping them in their most dire crises since the founding of the country, and if the feds impose the heavy hand of martial law without any benefit to the states, they will have less incentive to remain a part of the union.
Note 2: What would the break up of America mean for the dollar and for gold? It would likely be very bad for the former and very good for the latter.
