Wealth without workers, workers without wealth

The digital revolution is bringing sweeping change to labour markets in both rich and poor worlds

First, the rise of machine intelligence means more workers will see their jobs threatened. The effects will be felt further up the skill ladder, as auditors, radiologists and researchers of all sorts begin competing with machines. Technology will enable some doctors or professors to be much more productive, leaving others redundant.

Second, wealth creation in the digital era has so far generated little employment. Entrepreneurs can turn their ideas into firms with huge valuations and hardly any staff. Oculus VR, a maker of virtual-reality headsets with 75 employees, was bought by Facebook earlier this year for $2 billion. With fewer than 50,000 workers each, the giants of the modern tech economy such as Google and Facebook are a small fraction of the size of the 20th century’s industrial behemoths.
