You are a low-level dunce. 5% a year is 5% a year. Using your logic one can say the cumulative cost of peanut butter has been huge since Bush took office.
Price of peanut butter depends on its demand and is set in the market-place. The price of govt depends on what? You constantly keep showing your ignorance of basic economics. The cumulative increase (decrease) is a perfect way of showing what he has done overall, and not just one year. Shut your mouth and look at S3. If you can read, you can understand it.
