The White House has given us a great online tool, "Your Federal Taxpayer Receipt."
Put in your Social Security, Medicare and income tax payments. Calculate your receipt.
The receipt will show you how much of your money goes to the Pentagon, to pay interest on the national debt, to veterans' benefits, to health care and so on.
It is very interesting, worth checking out on this tax day -- which is also, by the way, the Global Day of Action on Military Spending.
