In the New York Times, columnist Paul Krugman writes:
Over the last few years China, for its own reasons, has acted as an enabler both of U.S. fiscal irresponsibility and of a return to Nasdaq-style speculative mania, this time in the housing market. Now the U.S. government is finally admitting that there’s a problem – but it’s asserting that the problem is China’s, not ours.
And there’s no sign that anyone in the administration has faced up to an unpleasant reality: the U.S. economy has become dependent on low-interest loans from China and other foreign governments, and it’s likely to have major problems when those loans are no longer forthcoming.
