I'll pivot back to something Mr. Roberts said, which was about this not being the be-all and end-all. I think that's entirely fair. It really does matter where the money goes. It's all about how much wealth we are generating as a country, and then where the wealth goes is very much the stuff of politics. That's all fair; I don't disagree with that.
To that point, the impact of this is how wide our horizon is as a country. If we're not a very productive economy compared to our neighbours, then it just forecloses options for us in the future. It forecloses options in terms of how we deal with problems like climate change, reconciliation and poverty. It just limits the real resources that we have at our disposal for dealing with those social problems and for enjoying a high standard of living.
