Capitalism brings recession every four to eight years -. Shouldn't there be a plan to shield the population from the effects?

All economies have ebbs and flows. Ideally the Fed and other central banks in other countries endeavor to manage interest rates up or down to try and maintain steady economies. Because no one in their right mind wants a crash. But obviously crashes do happen when markets get impacted by people’s decisions.
The rest of us just ride the ebbs and flows.
