Banana Republic, Without the Bananas…or the Republic How does an economy like this keep going? It depends on the kindness of strangers and the stupidity of friends. Who but a fool or a friend would buy a U.S. 30-year treasury bond at a 4.28% yield? This number is only a few basis points from the number for annual increases in consumer prices. Which means, if all goes well, investors can expect to make a return of zero on their investment over the next 30 years. And if all this talk of Zimbabwe economics and banana republic finances turns out to be true, they can expect to suffer another round of losses - measured in the trillions. And why shouldn't it be true? The American Empire is a bit like General Motors, says Martin Hutchinson. It has heavy fixed costs, an aging workforce, worn-out equipment, mammoth debts, and it is losing market share. At immense cost, America maintains its legions in more than 100 overseas garrisons. At home, the mobs call for bread. And every candidate for office - save the forgotten man, Dr. Ron Paul - offers more of it. "We cannot afford another year without decent wages because our leaders could not come together and get it done," said Barack Obama in South Carolina.
