No one likes “price gouging.” Kevin Williamson explains at National Review Online why we need it.

Price gouging is treated as moral abomination and, at times, as a legal offense. You know what price-gouging is? A public service. Prices are how we ration scarce goods, and the pain associated with paying unusually high prices is how we learn not to put off laying in supplies until after the disaster has already happened. The guy with supplies to sell has, either through luck or foresight, managed to put himself in possession of what you need — and you did not. You don’t have to thank him, but you do have to pay his price. The profit he makes encourages him to keep planning for the future. If that hurts — it should. Maybe you’ll learn to do better next time. But the alternative to paying the higher prices isn’t paying a lower price — it is having no gasoline or water or toilet paper at all, at any price. You can try to regulate away that reality; ask the Venezuelans how that’s going for them.
