This week we look at the links between the US trade deficit, the low savings rate in the US, home prices, and interest rates, all in an effort to answer the question: "Do trade deficits matter?" I think I will offer a few practical, if simple, insights to the matter.

At the end of last year, I did a series of e-letters on the debate over dinner in London between Bill Bonner and Charles and Louis-Vincent Gave. Both had just published a book. Bill's book, Empire of Debt (which is still doing well) states that the US trade deficit, coupled with massive government and consumer debt, is going to drive the dollar to its knees and end up with the US in a soft depression. You can chalk it safely in the doom and gloom column.
