But, actually, I think it's for the better because, as I said earlier, we actually want broad based - low rate taxes. We want to have the same rate across all incomes so that we don't distort people's decisions. We don't want to continually hollow out the tax base by giving an exemption on some income, necessitating tax rates on other incomes to be higher than they would otherwise be. In other words, we don't want to keep raising the threshold for the bottom rate, because that means we have to have higher tax rates on higher incomes. That's actually more distortionate. It's less fair because it means that people who earn more income don't just pay more tax because they earn more income; they pay disproportionately more. The more that tax thresholds are indexed to inflation, the more of the effect I've just described you get.
