It follows that it is just as essential for the health of a dynamic economy that dying industries should be allowed to die as that growing industries should be allowed to grow. For the dying industries absorb labor and capital that should be released for the growing industries. It is only the much vilified price system that solves the enormously complicated problem of deciding precisely how much of tens of thousands of different commodities and services should be produced in relation to each other. These otherwise bewildering equations are solved quasi-automatically by the system of prices, profits, and cost. They are solved by this system incomparably better than any group of bureaucrats could solve them. For they are solved by a system under which each consumer makes his own demand and casts a fresh vote, or a dozen fresh votes, every day; whereas bureaucrats would try to solve it by having made for the consumer, not what the consumer themselves wanted, but what the bureaucrats decided was good for them.
