I think it was interesting when our colleague David Seymour pointed out that that's exactly what Labour did 21 years ago. How long did it take before people started creeping up towards that income level? Now, of course, 21 years later, where that level was set is now below what the mean income is for New Zealanders. So you do get a lot of movement over a period of time, and it seems to me that the idea that you're going to say, "Well, at the $180,000 mark you meet something magical and you must pay more tax." denies the fact that everybody in this country wants, eventually, to see their incomes rise.
