With the best will in the world, you cannot artificially maintain an economic model that is no longer viable. I think Muldoon tried something like that. New Zealand cannot isolate itself from the rest of the world. If our retail sector is so vulnerable to foreign competition it cannot survive in the long term anyway. Rather than trying to protect it with unsustainable measures, it needs to evolve into something that can compete.
It is not relevant to this discussion, but as a point of information my pension is not paid in this country. It comes from the Netherlands.
