The US takes in nearly 4 trillion dollars. Might be 4 trillion given the current economy.
So, we have spenditures of Defense Department, State Department, Veterans Affairs, Justice Department, and the cost of the three branches of govenment, leg, jud,exe.
That is roughly 811.1 billion dollars.
Put Social Security and Medicare into separate budgets AWAY from the Federal budget and use ONLY the reciepts they get from taxes to pay out with.
That means we can apply 3 trillion per year to the debt, or we can cut...say...a smooth 1.5 trllion in taxes and still manage to put 1.5 trillion a year toward the debt.
Will only take 100 years if income remains at current levels. Likely to go way up over that 100 years, making the debt decrease exponentially.
