But the next part of Mr Parker's analysis that I just think we need to look at, apart from his undying, completely yielding adherence to everything that the Treasury says, is this idea that the housing policy is working because, actually, we're building more houses now. Well, I would remind Mr Parker that in 1973 we were building 13 houses per 1,000 people of our population, and today we've managed to get it to about eight. So we are not building houses as fast as we have in the past, as a country, and it is completely false to claim that.
