John Key expects taxpayers to pay medical students to go to school. He expects those with very little to be taxed to subsidise those who can be expected to earn a lot.
This is presumably what it means to be "ambitious for New Zealand" -- to pick the pocket of Peter just to fill the pockets of Paul.
Subsidies have been the hallmark of National Governments past; they will clearly also be the hallmark of would-be National Governments of the future.
It's like the bad old days all over again, isn't it.
