Milton Friedman Explains Inflation in 2 minutes

Inflation is defined by an increase in the money supply. The US has created trillions of dollars out of thin air. Doing so decreases the relative value of each dollar, therefore you need more dollars to buy the same amount of things as before. It's not Putin, the war in Ukraine, greedy gas station owners, etc. It's us allowing trillions to be created out of thin air.
