So this isn't any sort of moralising thing. If you believe in fairness and if you believe in justice, then there has to be redistribution, because it is a mathematical fact that a smaller and smaller number of people will become wealthier and wealthier, irrespective of what contribution they have made to society. It's just maths—look it up. So the Green Party will be here talking about having an actual fair tax system, and to do that, we're going to have to make structural changes which mean that the very wealthiest do contribute a fairer share to the group here in New Zealand—to the team of 5 million—that we all benefit from. We will all be better off when that happens.
