Some people might say, "Well, this is just one instance. We're on new ground here." Actually, I think it is important that public policy is evidence-based. We, over the last 40 years, have had the benefit of enormous evidence of over $2 trillion of privatisations, and there have been studies—there have been studies of those studies—there have been people like Phil Barry, the economist here in Wellington, who have played a role in evaluation the effects of shifting Government enterprises from public ownership to private. And guess what! Private and privatised entities, in the long run, on average, over time, outperform public entities like for like in terms of productivity.
