Here is Paul Krugman in his element discussing economic policy and the history of the Great Depression.

In the early 1930s this mentality led governments to raise interest rates and slash spending, despite mass unemployment, in an attempt to defend their gold reserves. And even when countries went off gold, the prevailing mentality made them reluctant to cut rates and create jobs.
But we’re past all that now. Or are we?

Consider first the current uproar over the declining international value of the dollar.
The truth is that the falling dollar is good news. For one thing, it’s mainly the result of rising confidence: the dollar rose at the height of the financial crisis as panicked investors sought safe haven in America, and it’s falling again now that the fear is subsiding. And a lower dollar is good for U.S. exporters, helping us make the transition away from huge trade deficits to a more sustainable international position. But if you get your opinions from, say, The Wall Street Journal’s editorial page, you’re told that the falling dollar is a terrible thing, a sign that the world is losing faith in America (and especially, of course, in President Obama). Something, you believe, must be done to stop the dollar’s slide. And in practice the dollar’s decline has become a stick with which conservative members of Congress beat the Federal Reserve, pressuring the Fed to scale back its efforts to support the economy.
