The American model remains an impressive growth engine, even allowing for the debt-fueled bubble. The U.S. economy grew by 63 percent between 1991 and 2009, compared with 35 percent for France, 22 percent for Germany and 16 percent for Japan over the same period. In 1975, the U.S. accounted for 26.3 percent of world G.D.P. Today, after the rise of the Asian tigers, the U.S. actually accounts for a slightly higher share of world output: 26.7 percent.
The U.S. has its problems, but Americans would be crazy to trade their problems with those of any other large nation.
