The federal government is operating at a huge annual budget deficit, spending much more than it is receiving in tax revenue. The extra money must be borrowed, as of the Summer of 2017,about 15 cents on every dollar spent by the Federal Govt. From whom is the government borrowing about a trillion dollars a year? What are the advantages and disadvantages to borrowing this much money? What if we can't pay it back? What happens if lenders lose confidence in the US government and are no longer willing to lend?
