The central bank is generally able to bring the economy out of a recession by easing rates to stimulate the cycle anew. But over time, each bottom and top of the cycle finishes with more economic activity than the previous cycle, and with more debt. Why? Because people push it—they have an inclination to borrow and spend more instead of paying back debt. It’s human nature. As a result, over long periods of time, debts rise faster than incomes. This creates the long-term debt cycle.
