The only answer I've heard so far is that it was Andrew Bayly's idea, not theirs, and why didn't we do it in Government. Well, I've just told the people that. We didn't actually have the mechanism to do it, because the system that we inherited in Inland Revenue—the computer system—was so overburdened that every time there was a change to anything, it was, basically, a matter of holding your breath to see if it all fell over, and that's why we had to spend about a billion dollars doing it.
