I fully support Leith van Onselen’s view on infrastructure investment:
It is important to (as much as possible) take the decision-making for infrastructure investment away from the political process and instead place it in the hands of an independent authority tasked with maximising overall welfare and productivity at lowest cost. Picking infrastructure winners, based on preconceived ideas or political motivations, is a recipe for waste and is likely to end up being productivity-destroying for the economy at large.
