Detroit was once the greatest city of the modern world. Automobiles were the cutting edge of technology in the first half of the twentieth century. Talent and genius flocked to Detroit. Innovators in engineering, technology, design, finance, marketing, and management created a concentration of economic dynamism and creativity unlike anything the world had yet seen. Detroit was the Silicon Valley of its day, except its products were made of tangible metal, rubber, and glass. The auto industry transformed America into a land of mobility and personal freedom beyond the dreams of earlier generations. Henry Ford said, “History is bunk.” He meant the old limits could be blown away, and ordinary people could have a better life than they had ever dreamed of before.
