@donasmrs-- It's not that confusing. Let me try to simplify it for you.
There are four basic steps in a business cycle: growth, boom, downturn and recession. Inflation (or high inflation) is what happens during an economic boom. If the inflation is not managed at this stage, then the economy takes a downturn and eventually goes into a recession.
It sounds like inflation and recession are unavoidable due to the nature of the business cycle but that's not exactly true. That's why we have monetary and fiscal policies. And these policies are not very difficult to determine and use either. For example, in most cases, an increase in interest rates by the Central Bank will be enough to reduce inflation during the economic boom stage.
