OPINION: Accountants are good people to blame when you run out of anybody else to. Still, I find it odd to be blaming this accountant I met at a recent migrant protest for the low-productivity situation we find ourselves in. The word ‘productivity’ has been rearing its head recently, but not the way we once knew it. During the 1980s and 1990s it was used to justify major economic reforms and lift output, but these days it is more commonly heard in relation to migrants who are being accused by various ministers and economists of spreading economic growth too thinly through the mere act of moving here.
