On Thursday night, I saw the movie, “I.O.U.S.A.,” which focuses on the national deficit. It has been hailed as “An Inconvenient Truth,” without a celebrity-type lead like Al Gore, but I found it equally interesting. While it’s not a “sexy” topic (as one man in the film kept reminding everyone), unlike global warming, it’s something we can all agree on: Our nation is in debt up to its ears and way past that.
