“Producers, being self-interested humans, will not sell a good for a price that does not cover their entire cost of production. They would rather go out of business and stay home than work in a business that loses them money. So trying to mandate lower prices simply results in the destruction of the human incentive to produce a good, resulting in higher prices and even lower supplies. The other inevitable consequence of price controls is the emergence of black markets where the seller and buyer can transact at rates suitable to both of them, but without the attention of the government.”
