ONE hundred years ago today, President Woodrow Wilson went before Congress and demanded that it “act now” to create the Federal Reserve System. His proposal set off a fierce debate. One of the plan’s most strident critics, Representative Charles A. Lindbergh Sr., the father of the aviator, predicted that the Federal Reserve Act would establish “the most gigantic trust on earth,” and that the Fed would become an economic dictator or, as he put it, an “invisible government by the money power.”

Had the congressman witnessed Ben S. Bernanke’s news conference last week, he surely would have felt vindicated. Investors, traders and ordinary citizens listened with rapt attention as Mr. Bernanke, the Fed chairman, spoke of his timetable for scaling down stimulative bond purchases. “If things are worse, we will do more,” he said of the nation’s economy. “If things are better, we will do less.”
