How is it possible that the public sector is no more productive today than it was in 1996, before the internet took off?
Britain has a chronic productivity problem. As the American economy marches upwards in output per person, Britain limps behind. As Ben Southwood, Samuel Hughes and Sam Bowman have calculated, if GDP per hour worked here had continued growing at the rate it grew between 1979 and 2008, we would now be 25 per cent richer and annual tax revenues would be £274 billion higher.
