"The claim that real wealth can only be achieved by making things falls

on receptive ears. You can’t have an economy of hairdressers, the saying

goes. Yet you can’t have an economy of steelworkers either. Mao Tse

Tung tried this: he encouraged the creation of backyard furnaces in

which peasants melted down pots and pans to meet national targets for

steel output. But the experiment is not generally regarded as a success.

The productivity of modern economies is based on the division of

labour."
