When it comes to things that are public goods—and transport is one of those things where it's very difficult to commercialise the full benefits, and the impacts of transport infrastructure and transport vehicles are far beyond the individual people using them. Airplanes have an impact on the climate, they have an impact on the people who live near the airports, they have a benefit for the people who are flying on the airplanes, but they also have external impacts. It is entirely appropriate in this day and age, where we've seen—post the global financial crisis, post-COVID—in the age of needing to respond urgently to climate change, that that failed ideology of the 1980s and 1990s, which is still well and alive in the most right-wing parties in our Parliament—has been proven wrong. We cannot rely on individual organisations focusing on maximising their own private monetary profit to deliver better outcomes for the whole world. It's just not going to. That should be obvious.
