So I guess—just to conclude the questions—does he have any advice on it, and does he understand what the effect might be on the propensity of people to work and the propensity of people to migrate to New Zealand, because it really matters that we're able to get people to work, save, and invest, and also come to this country. There's at least a prima facie case that increasing the top marginal tax rate will discourage people from doing that and that there are wider dead-weight losses to the economy from having a higher tax rate. If the Minister can tell us whether he's had any advice about those questions and what that advice was, I would be very grateful.
