I have been in South America this week, speaking nine times in five days, interspersed with lots of meetings. The conversation kept coming back to the prospects for the dollar, but I was just as interested in talking with money managers and business people who had experienced the hyperinflation of Argentina and Brazil. How could such a thing happen? As it turned out, I was reading a rather remarkable book that addressed that question. There are those who believe that the United States is headed for hyperinflation because of our large and growing government fiscal deficit and massive future liabilities (as much as $56 trillion) for Medicare and Social Security.

This week, we will look at the Argentinian experience and ask ourselves whether "it" - hyperinflation - can happen here.

I will be quoting from Niall Ferguson's recent book, The Ascent of Money. I cannot recommend this book too highly. In fact, I rank it up with my all-time favorite book on economic history, Against the Gods, by the late (and sorely missed) Peter Bernstein. There are very few books I read twice. There are too many books and not enough time. This book I will have to read at least three times, and soon, and I have a lot of underlines and mark-ups in it already.

If there were one book I could require every member of the Congress to read, it would be this one. As I read it, I am struck again and again by how fragile and yet resilient our economic systems are. Fragile in the sense that governmental policy mistakes, no matter how well-intentioned, can destroy the wealth of a nation, and resilient in that it doesn't happen more often.
