In the words of David Autor, a leading labour economist at Harvard University, the labour force is suffering from a growing “missing middle”.
In short, the middle-skilled jobs that once formed the ballast of the world’s wealthiest middle class are disappearing. They are being supplanted by relatively low-skilled (and low-paid) jobs that cannot be replaced either by new technology or by offshoring – such as home nursing and landscape gardening. Jobs are also being created for the highly skilled, notably in science, engineering and management.
