I don't disagree that there is a lot that Australia does right and the US would be better off with an Australian style system complete with a universal healthcare. Australia could have gone the NHS route but did pivot to the mixed system under Howard. Additionally it does appear to me that the National Disability Insurance Scheme is absolutely rife with fraud - I'm not even sure who'd you'd blame for that as it seems intentionally set up for such an outcome to undermine the very idea. So I'm not sure how well the Australian system will last even if it has lasted well up until now. Of course being Australia they'd combine NDIS with Robo-Debt and mistakenly hound a bunch of poor people to death.

I'm assuming the rational behind drawing the distinction between the US and Aus systems is to somehow inform what the US should do, I don't think giving an already corrupted government system more power will help. It's very hard to uncorrupt things and because of that reason I think the US would benefit from a more laissez-faire system.

Additionally Australia has many advantages that the US does not and the US could not emulate Australia even if they wanted to. I don't know how long that'll last either - mathematically I would assume a country could not get rich and stay rich repeatedly selling houses to each other but it does seem to have lasted a very long time. I assume at some point the Aus government will run out of ways to prop up the housing market. The combination of negative gearing and all sorts of first home buyer grants is just insane.
