'In reviewing Alex Millmow's biography of Colin Clark, I should begin with disclosure of my own interests. When I first became politically aware, in the early 1970s, I knew of Clark as something of a fringe figure in Australian public policy debate, closely associated with B.A. Santamaria. He was prominent both as an extreme anti-Malthusian, claiming that the world could support a population of 50 billion, and for the proposition that the ratio of taxation to national income could not exceed 25 per cent without dire consequences. I was not sympathetic to either view.' (Introduction)
