“Inflation is everywhere and always a monetary phenomenon” Milton Friedman.
Printing too much money above equal increase in production of goods and services... Or in our case, stimulus checks with declining production means high inflation.
Add in anti-price gouging laws caused by state governments enacting state of emergency plans (producers are legally forced to sell products below market equilibrium) and therefore there are shortages. Ka-Boom!
