I don't know, Steve. All the folkie things I've been involved in have been much further left than society in general, but equally there have always been some who aren't. I know someone who has a song about being the only Tory in the folk club.

And I think their presence and criticisms are essential. I said below that I have more respect for those who say Brexit will have problems but on balance they still think it right than I do for those who think it is getting better every day in every way. The same is true for left wing policies: I have more respect for those who realise the cost but think that is worth bearing, than who don't think about it. Let me give an example: at the moment there is a movement to get rid of the 55p per minute phone charge for the Universal Credit help line. I agree - it should go. But these things do not run entirely free. If these costs are offset something will give, either in funding for something else the government does, or income to the phone company, which will probably end up or contribute to some poor soul near the bottom losing their job. That is a hard thought, but in the full understanding it may happen I think the 55p charge should go.

We see the same thing the whole time with NICE: a drug is turned down as too expensive, so a campaign is mounted, pressure is put on the government and the committee and somehow the money is found. The campaigners rarely face up to the fact that in the process they have almost certainly increased the pain and suffering of some other group.

So we need critics to make sure we are properly aware of the implications of decisions we make, because none of us have a full understanding of the issues that might arise. Now it is true that too many of the right stop when they have worked out the balance sheet implications, but some think beyond that.
