In two parts, BBC Business Editor Robert Peston examines how the global financial crisis came to be, and how the shifts in the world economy have left the UK in need of a radical economic overhaul. `The Party's Over' begins by comparing 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.
