| The U.S. expansion appears on track. Europe and Japan may lack exuberance, but their economies are at least on the plus side. China and India -- with close to 40 percent of the world's population -- have sustained growth at rates that not so long ago would have seemed, if not impossible, highly improbable.
Yet, under the placid surface, there are disturbing trends: huge imbalances, disequilibria, risks -- call them what you will. Altogether the circumstances seem to me as dangerous and intractable as any I can remember, and I can remember quite a lot. What really concerns me is that there seems to be so little willingness or capacity to do much about it.
We sit here absorbed in a debate about how to maintain Social Security -- and, more important, Medicare -- when the baby boomers retire. But right now, those same boomers are spending like there's no tomorrow. If we can believe the numbers, personal savings in the United States have practically disappeared.
