At present I am in transit in Dubai waiting to fly home to Sydney after a week or more away in Central Asia. I am definitely being careful to avoid any public swearing, which means I am not reading any economics or business reports in public spaces. With the worry that I might swear out aloud and get stuck here, I judiciously completed all my reading in the privacy (assumed) of my hotel room at the airport. Lucky. Imagine what would have happened if I had been reading this article – David Cameron’s tonic to snap us out of recession – out on the concourse?
