In the first of two programmes BBC Business Editor Robert Peston examines how 30 years ago, momentous decisions were taken which shaped the world we live in today. In China, Deng Xiao Ping opened up the country to foreign capitalists; in Britain and America, the free market revolution was unleashed by Margaret Thatcher and Ronald Reagan. The Party's Over compares the lives of workers in a Chinese company with their co-workers in Britain. Peston interviews bankers, politicians and economists, concluding the boom we enjoyed before the crash was based on an illusion, and that the world's economy is now so unbalanced that in the West we face a sobering wake-up call.
