THE great Calvin Coolidge reputedly said that "the business of America is business." These days the business of America is carpet-chewing rage. American politicians are intent, not on improving their country's competitiveness, but on gouging each other's eyes out.

American companies are sitting on a gigantic pile of cash; Apple alone has $76 billion in the bank. Why won't corporate America invest in America? It does not help that domestic demand is feeble, and that the global economy is in turmoil. But American politicians deserve some of the blame. Their unpredictability erodes confidence. The gulf between American business and the Obama White House is growing ever wider, as business-friendly insiders (such as Larry Summers, an economic adviser) leave the administration. Even more dangerously, the gulf between business and the rest of the country is widening: opinion polls show that American businesspeople are losing faith in their country even as ordinary Americans are losing faith in business. Calvin Coolidge's statement was once denounced as the height of bourgeois complacency. Today it sounds like a reminder of an America that is in danger of disappearing.
