I think an analogy may help.
People often use total electrical usage as a measure of the health of the economy. Like debt, electrical usage is loosely associated with economic activity and growth.
After the spike in oil prices during the late 1970s, factories and other users of electricity became more efficient. In the following decades, growth in electrical usage was stagnant and often declined. Those who viewed this as an indication of serious problems with the economy were misled.
If the Fed had promoted increased usage of electricity, or subsidized the cost of electricity - paid for with a tax on savers, economic growth would not have been enhanced - indeed it would have increased costs and made America less competitive.
While this may seem obvious to many, the same people who find this concept absurd naively believe growth is enhanced if the Fed promotes the use of debt, or subsidizes the cost of borrowing money - paid for with a tax on savers.
Debt creation is loosely associated with economic activity and growth, just like electrical usage is, but the economy would be more efficient and enjoy lower costs if America weaned itself from excessive reliance on debt.
