Politicians, for example, are apparently completely baffled by Poor People’s propensity to do harmful things, often expensively, to themselves. (That’s politicians of all stripes – it’s just that the left wing wrings its hands and feels helplessly sorry for Them, while Tories are pretty sure They are just animals in need of better training.) The underclass eats fast food, drinks and smokes, and some of its more unruly members even take drugs. Why? Why?

Listen, I always want to say, if you’re genuinely mystified, answer me this: have you never had a really bad day and really wanted – nay, needed – an extra glass of Montrachet on the roof terrace in the evening? Or such a chaotic, miserable week that you’ve ended up with a takeaway five nights out of seven instead of delving into Nigella’s latest?

You have? Why, splendid. Now imagine if your whole life were not just like that one bad day, but even worse. All the time. No let-up. No end in sight. No, you can’t go on holiday. No, you can’t cash anything in and retire. No. How would you react? No, you’ve not got a marketable skills set. You don’t know anyone who can give you a job. No. No.
