Recently, colleagues of mine were asked how to promote the habit of recycling domestic refuse. They explained there was no need to mention the environmental benefits at all. ‘Just make sure everyone has two pedal bins, not one.’ Regardless of people’s attitudes to the environment, what really matters, as Martin Luther King might have said, is not the colour of their politics but the contents of their kitchen.
To encourage pension saving, the government spends more than £20 billion annually in tax rebates. To swathes of the population, this enormous and wasteful incentive is entirely unmotivating.
