JazzG Sounds like a great plan, now I just need to figure out who in the government would actually do this!
See, this really lays out the stakes of claims about "political reaction".
When I say Australia has implemented militarised turnbacks of asylum seekers on the way to becoming a national polity that is more racist and more paranoid, all while a succession of its governments have been implementing a delirious wealth transfer through bad tax policy, and stubbornly delaying a sane policy on housing …
… I am offering you a pretty fair-minded Australian history to serve as the result of a simplistic, but at least possible social-scientific enquiry that has already been underway, here, into a hypothesis we can share that would be "unlawful migration is a decisive social and economic problem for the de-industrialising nation-states of the core of the declining United States-led world order" or something like that.
Australia stopped the boats. None of the other political terms we would agree are at stake could be said to have improved as a consequence. Housing is no more affordable. Jobs are no more available or rewarding. The concentration of wealth has not abated. Social cohesion is not a solved problem. Racism is certainly not a solved problem.
The Australian results of the experiment are for the null hypothesis.
To me we disagree with each other on a regular basis, but only one of us seems to perceive our varying orientations to history are at fault. Your lot are still talking about how "communism has been failed wherever it has been tried" as if my lot is full of schematic Marxist-Leninists, while you sit gnashing your teeth in the crumbling edifice of the capitalist empire.
We, together, as in people like you and me despite our differences, do have a great opportunity to evolve our shared thinking.
For example, we could re-frame the claim "unlawful migration is a decisive social and economic problem" not solely in terms of the contents of bordered states—populations, workforces and domiciled businesses among others—but also in the terms of the bordering structure. People and investments crossing borders have effects, but not only the effects the national vantage point is useful to perceive.
