Just as well this isn’t France. A few days ago, about a million people took to the streets to complain that President Macron was raising the retirement age to… 64. Naturally public sector workers were especially prominent: the self-employed rather less so. But really, what are we complaining about? There is, as we all now know, a chronic labour shortage which neither robots nor AI can address. And if young people can’t be persuaded to work longer and harder, why on earth should we be subsiding perfectly healthy people in their 50s and 60s to loaf around? Personally, I’d pay pensions at 70.
