I suppose the social crisis counts a milder, Liberal Democrat version of David Cameron's broken Britain. It seems to consist in the lack of social mobility in modern Britain, which Nick characterises as a lack of "fairness".
"Fairness" always seems such a playground word, even if it does go down well with the focus groups. Nick says the concept "pierces right to the heart of everything progressives stand for", but it is hard to imagine something so wet piercing to the heart of anything.
Plus, as I have argued before, it is not that Tories don't believe in fairness; it's just that they have a different conception of it.
Anyway, Nick makes some good points about the burden of taxation the poor now bear, and the more familiar one that "a child born today in the poorest neighbourhood in Sheffield will die on average fourteen years before a child born in the most affluent neighbourhood a few miles away".
If I read that once more I shall be tempted to ask why he got himself selected for that affluent neighbourhood.
Then on to education and, inevitably, the pupil premium, though government micromanagement of schools gets a welcome kicking too.
On to health, where the same critique of Labour is offered. Then tax, where the lowest earners should be lifted out of it. And finally housing, where they key is to treat house price inflation like any other kind of inflation by taking it into account when interest rates are set.
Next time it will the security crisis and that really will be it. Except that I have just been asked to turn these jottings into a coherent article for Liberator.
