"...The truth is that no government in Britain in living memory has set out a sufficiently comprehensive and ambitious vision of this country’s infrastructure needs. And by a comprehensive and ambitious vision, I do not just mean a list of projects; I mean an overall system, an integrated set of networks that collectively deliver the economic and social goods."As well as this failure of vision, there has also been a failure of financing. Everybody knows that infrastructure is expensive; one academic assessment puts the bill at £500 billion just to meet our current commitments. And we cannot hide from the fact that new infrastructure has to be paid for either by those who use it, by government, or by a combination of the two."
