Today, a city of nearly five million people, Shenzhen, sits at the border. The hinterland behind Shenzhen, the Pearl River Delta, is the heart of the fastest growing industrial zone in the world, the Chinese province of Guangdong. This is the landscape that produces two-thirds of the world’s photocopiers, microwave ovens, DVD players and shoes, more than half of the world’s digital cameras and two-fifths of its personal computers. Guangdong’s business is to make things. It sucks manufacturing from Europe and North America and other economies with high wage rates, cheapens it, increases it, then ships it by container to overseas markets. The factories here bear no relationship to the ones I knew thirty years ago in Shanghai. It is as different as Manchester in the 1840s was from rural England in the eighteenth century and to come here is to feel a little of what Friedrich Engels felt when he set out to describe Manchester, the world’s first uncompromisingly industrial city. Here too, the visitor marvels at the industrial energy and is appalled by the degrading conditions in which the workers live. ‘In this place,’ as Engels put it, ‘the social war, the war of each against all, is here openly declared.’
