David Cameron (UK Prime Minister) has said that social housing should be allocated to those who work hard. It the kind of superficial comment we're used to from politicians of all persuasions. It doesn't really bear close examination.
First, how would someone determine how hard anyone is working, and second, there's a vector here. How hard anyone is working doing what? It does actually matter what they're doing. It needs to be socially constructive and in support of human needs - as well as being sustainable within the resources available. Do we want people working hard against these goals?
