It is interesting that the latest Australian surplus looks to be around $6.2 billion, which is less than the NZ surplus, and for an economy more than five times as large.
Our level of surplus, in Australia, would be over $30 billion. An Australian Government which claimed this was not big enough to afford tax cuts would be laughed into oblivion.
The refusal of Labour to give taxpayers some of their money back is not mainstream politics on the left or right. It places them almost alone in the developed world.
