"It seemed a miracle when West Germany—a defeated and devastated country—became one of the strongest economies on the continent of Europe in less than a decade. It was the miracle of a free market. Ludwig Erhard, an economist, was the German Minister of Economics. On Sunday, the twentieth of June, 1948, he simultaneously introduced a new currency, today's Deutsche Mark, and abolished almost all controls on wages and prices. He acted on a Sunday, he was fond of saying, because the offices of the French, American, and British occupation authorities were closed that day. Given their favorable attitudes towards controls, he was sure that if he had acted when the offices were open, the occupation authorities would have countermanded his orders. His measures worked like a charm. Within days the shops were full of goods. Within months the German economy was humming away."
