[...]Yet 3D printing is just one of many production technologies and trends which are transforming the way companies will be able to make things in the future. The old rules of manufacturing, such as “you must seek economies of scale” and “you must reduce unit-labour costs”, are being cast aside. New machines can print every item differently. More flexible robots are getting cheaper and better at doing all the boring and dirty stuff.
Add to that another 1.8 billion consumers who will join the global marketplace in the next 15 years and “Manufacturing the Future”, a new report by the McKinsey Global Institute, has good cause to be optimistic. Demand will grow not only for basic goods (which are typically made in developing countries) but also for the costly, innovative gadgets and high-tech products that rich countries make. McKinsey reckons that rich countries will keep making such products better than anyone else.
Developing countries will continue to increase their share of global production. Measured by nominal value added, by 2010 China had surpassed Japan to become the second-largest manufacturing nation, after America. A decade earlier it was in fourth place. In the same period, Brazil jumped from 12th to 6th and India from 14th to 10th. Britain slipped from 5th to 9th.
As countries get richer, manufacturing tends to account for a smaller share of their GDP. The point at which this decline starts varies (the share usually peaks at 20-35%), as does the rate of decline. In the 15 largest manufacturing economies, manufacturing’s share of GDP ranges from 33% in China to 10% in Britain (see chart).
Rich countries’ relative position may be slipping, but their absolute manufacturing output is rising quite fast. What has fallen is the number of workers needed on the factory floor. Even though some manufacturing is returning to America and Europe from places where it had been offshored, such as China, this trend will not recreate all the factory jobs that once existed.
[...]In the future, McKinsey predicts there will be more jobs for robots. Since 1990 the cost of automation has fallen relative to labour by 40-50% in the rich world, it says. The rise of the machines will continue in rich countries, and they will make inroads into developing ones. Wages in emerging markets are soaring. One Chinese manufacturer is talking of hiring 1m robots. Still, robots need people to build, program and maintain them. Humans have no cause to hold their heads in their hands.
