https://en.wikipedia.org/wiki/Constitution_of_Australia ?!?! I'm genuinely a little baffled by this. Reading about it, it looks like there are some important elements of the structure of the government that aren't part of the Constitution, most notably the office of Prime Minister not even being mentioned, but that's extremely different from there not being a Constitution at all.

I think that you need to find a better argument to promote a worker based economy. Perhaps the co-op based system in Italy, which has lasted longer, is a more sustainable way to go.

"X country was defeated, therefore a better example of a government is a bunch of cooperatives that exist inside of an imperialist state that is building up toward being taken over by fascists again."

I've got nothing against those co-ops, but this is apples to oranges and just seems like motivated reasoning.
