Interest Rate Tipping Point
At what average interest rate does interest consume all tax revenue?
At an average rate of 6.8%, half of all federal tax revenue would go to interest alone. At 13.5%, the government would need every dollar of tax revenue just to pay interest — with nothing left for defense, Social Security, or Medicare.
