The national debt will be $100 trillion by 2035

 This is a similar but slightly different calculation to the previous post.  I noticed that the national debt has been increasing at slightly more than a 10% rate from the year previous.  And elsewhere I saw a prediction from Social Security that GDP would increase at an average 5.5% pace.  Combine these and see what the national debt is a percent of GDP, and this is what you get.
