“Here is a principle to use in all aspects of economics and policy. When you find a good or service that is in huge demand but the supply is so limited to the point that the price goes up and up, look for the regulation that is causing it. This applies regardless of the sector, whether transportation, gas, education, food, beer, or daycare. There is something in the way that is preventing the market from working as it should. If you look carefully enough, you will find the hand of the state making the mess in question.”
