Concluding the documentary series on the history of money. The End or the Beginning? Peter Jay looks at the west's growing prosperity since the Second World War, and the disparity between this "success" and the fact that 80 per cent of the world's population live in poverty. A Tanzanian schoolteacher offers his view of life in the west and there's a look ahead to what society might be like 300 years from now. Producer Adam Salkeld ; Series editor Barbara Want (S) (W)
