The economy is the largest accident ever designed by man. We think we can’t control it, but people do. Unfortunately, it is our human nature that is in control and not our logic.
Trickle-down Reaganomics is one attempt at control. The idea is to give tax cuts to people that don’t need them. These people will then invest that money in their businesses, if they have one. They will hire workers, if they need them. They will buy more and better equipment, if it’s needed, etc. If you are having trouble comprehending the efficiency of this, you might be told it is because you don’t have an advanced degree in economics.
