Growing the economy will balance 80% of budget

The US is a marvelous economic machine with a 12-trillion-dollar economy. When you get an economy that large up and rolling with a 3 or 4% rate of growth, that stimulates enormous revenues for individuals and businesses. It also kicks off a lot of tax receipts to governments at all levels. Next, and the most important step by far, is to grow the economy. That may be 80% of balancing the federal budget.
