Really the debate should be about, how we can keep Australia functioning as a first World economy and the best way to facilitate it.
Our electricity/energy costs are stupid, our road and rail infrastructure is ancient and causes bottlenecks everywhere, our ports are still set up like we are still in the 1920's.
All these problems cause loss of productivity, every truck stuck in a traffic jam, is a loss in productivity. Every ship sitting out in the outer harbour waiting for a berth is a loss in productivity. Every train waiting in a siding for hours, to let another train going in the opposite direction past, is a loss in productivity.
Some job is sitting idle waiting for something on that truck, or that train, or that ship.
Australia to become competitive, has to think about how it does things and what it wants as a final outcome with regard living standards.
Just my opinion.
