It gets worse: in this Budget, Treasury hasn't presumed any projections for fair-pay agreements, and we explain how that will roll back into GDP forecasts. Following the Government's announcements on net immigration, the Reserve Bank admitted to us the other day that they've never even received a memo from the Government on how this will affect maximum sustainable employment. So where do we go from there if the Government's making decisions, and Treasury and the Reserve Bank can't actually model the future? That means that for everybody who's sitting at home with a pen and paper at the weekend trying to balance their budget, from the working solo mum up to the people who've not been property flippers but actually wanted to build their pension nest eggs, uncertainty abounds and reigns.
