The economic policy arguments, by the way, will all be about what policies might gain or lose those few percentage points. In 2020, there will probably be, at a rough guess, an extra couple of million people working, compared with today’s 11.3 million. But exactly how all those people working will earn their living and go about their work is considerably less predictable.
A good proportion of those 13 million-plus jobs will be in firms that don’t yet exist. Some will be in industries or occupations that barely exist as yet.
