Great write-up.
In fact, the line “Labour and National had broadly similar fiscal approaches…” is worth repeating.
So the default position we should be applying to the current government is – where is all the evidence for the claims that Luxon is making?
I don’t see why it couldn’t be, either with some sort of legislated review period or formula to calculate the threshold.
In any case I’d prefer having one alongside our non-indexed tax system to not having one at all
