GDP is not the government income. Why don't we look at the "total income" the government takes in, in taxes, fees, and levies, to calculate a debt to income ratio?
The national debt is debt each taxpayer will have to shoulder. Our children will have to pay much of this debt eventually as you cannot simply ignore the amount. The national debt is currently at 6.4 trillion dollars. It is taking close to 360 billion dollars per year to pay interest. That is the fourth largest piece of the budget behind Social Security payments, Medicare and the Defense Department. In a 2.2 trillion dollar budget, the first 360 billion dollars goes to service the debt because the US will not default on the bonds. That number is staggering and continues to grow with Bush and the War and his tax cuts and the fact that he has NOT asked the American people to make any sacrifices.
More debt means more issuance of bonds ... this affects long-term interest rates and eventually inflation and the economy as a whole.
I am not saying we should pay off the debt but we must start the process to pay the debt down. 6.4 trillion dollar debts, wars and higher defense and homeland security spending in the future, Baby boomers retiring and going on Medicare and SS. If you think taxes are high now, just wait until this perfect storm hits.
