How do you measure the size of an economy?
GDP, right?
By that measure, US is the biggest economy in the world today with GDP in excess of $20 trillion. That’s the total value of the goods and services the country produced in FY17. The churn out of that kind of produce was achieved on the foundation of $12 trillion of national debt.
It’s not surprising to anyone that largest economic powerhouse runs and grows on the engine fuelled by debt.
