Germany destroyed its own price controls in 1948 and watched an economy resurrect itself inside eighteen months. Ludwig Erhard did it unilaterally. On June 20, 1948, he abolished the Nazi-era price and wage controls that the Allied occupation forces had maintained, then went on radio to tell Germans what he had done before anyone could stop him. The American occupation authorities were furious. General Lucius Clay demanded an explanation. Erhard told him he had not reformed the controls, he had abolished them. The results were immediate. Goods reappeared on shop shelves within days. Germans who had been hoarding anything of tangible value started trading again because currency reform and price liberalization made holding marks rational for the first time in years. Industrial output rose 50 percent in the six months following the reform. The villain in this story is price controls, and the economists and bureaucrats who insist they tame chaos rather than create it. Price controls tell producers to stop producing and tell consumers to hoard. Every time. The postwar German black market proved it: the official economy was starving while the illegal economy fed people. Erhard simply liberated the black market by freeing prices. You benefit from this history whether you know it or not, because it settled an empirical argument that interventionists have been trying to reopen ever since. Free prices coordinate production without a central planner. Suppress them and you get empty shelves and queues. Germany in 1946 had both. Germany in late 1948 had neither. The so-called Wirtschaftswunder, the economic miracle, was not miraculous; Erhard applied basic economic logic that Friedrich Hayek had already formalized in 1945 in "The Use of Knowledge in Society." No central authority possesses the dispersed, local, constantly changing information that prices aggregate and transmit. Bureaucrats trying to set correct prices are not just inefficient; they are epistemically incapable of the task. Hayek made the theoretical case, thrn Erhard ran the experiment on a starving nation, and proved it. West Germany grew at roughly 8 percent annually through the 1950s. East Germany, running Soviet central planning across the same ethnic population with similar prewar industrial infrastructure, stagnated and eventually built a wall to prevent its citizens from leaving. That comparison is about as clean a controlled experiment as political economy ever produces. Same people, same history, radically different institutions. The lesson: prosperity flows from secure property rights, sound money, and voluntary exchange. Erhard gave West Germans all three in one afternoon.
