Book excerpt: * It was 'the most modern city in the world, the city of tomorrow'. But the Fifties witnessed one of the greatest economic slides of the last century, as Detroit, formerly a beacon of the capitalist dream, degenerated into the urban wilderness it is today, where trees grow from the rooftops of derelict buildings and wild pheasants roam the long-empty parking lots. * By the end of the nineteenth century Detroit was thriving. 1913 saw the arrival of Henry Ford and the Model T plant, mass-producing cars and transforming the area into the Silicon Valley of its day. By the mid-1950s General Motors had become the single biggest employer on earth, and Detroit the fourth largest city in America. * But by the time Berry Gordy founded Motown Records in 1960 - creating Detroit's other great assembly line - the cracks were already beginning to show- big industry was looking elsewhere for cheaper sites, cheaper labour and better tax breaks; urban planning was in meltdown; corruption was rife; racial tensions were running high. * The 1967 riots - at the time the worst in US history - left 43 dead, more than 7,000 arrested and 3,000 buildings destroyed. Detroit, a former beacon of the capitalist dream, had degenerated into an urban wilderness where unemployment ran at 50%. With more guns in the city than people, the murder rate was the highest in America - three times that of New York. * Mark Binelli returned to live in his native Detroit after a break of many years. He tells the story of the boom and the bust - and of the new society to be found emerging from the debris- Detroit with its urban farms and vibrant arts scene - Detroit as a laboratory for the post-industrial, post-recession world. Here's what an iconic rust-belt city now looks like and how it might transform and regenerate itself in the twenty-first century.
