OP I don't see any discussion of the reasons to do all this. Everyone's going to assume it's yet another instance of knee-jerk reactionary racialism. "I just want to go back to when people like me had an unfair advantage". Yeah ok bro that's basically a stupid an uncharismatic motivation. You need to articulate the really solid objective reasons why society can't continue without doing this.
What the complex systems argument did so well was provide a very solid objective analysis that wasn't just dismissible as race-anxiety. What's the observable reason why the 1965 immigration specifically was worse, and needs to be reversed? I'll try to think of a few:
In the Denmark case (which obviously needs to lead such an article) the convincing problem was "they aren't integrating into our society and respecting our way of life, they are very disproportionately criminal, and they don't even pay net taxes into the pensions." (We don't want to lean too hard into some aspects of this because western "values" are retarded and mass pensions are inherently insolvent, but this is what played well politically).
I liked Arctotherium's recent article for providing an objective economic analysis of how ethnic cartelization is an inevitable result of mass migration and just bad for the economy. Even if the newcomers do good work, the market fragmentation externalities are really bad. This can obviously be extended to all manner of social things as well. It becomes "our kind can't really go to that neighborhood/city/region/industry/festival/etc anymore". You no longer live in a society, but only a caste. This is an argument for strong integration into WEIRD society.
A state is existentially dependent on its human capital and social substrate, but current states are acting like you can just trash the intangible trust and health of society and replace your high quality population with low quality people who have never really been civilized and everything will be just fine. It's totally insane.
There's a sort of precautionary fence argument against importing a ton of random foreigners who may stress your social systems in ways you aren't even prepared to imagine. This isn't even hypothetical anymore, so you can (and should) dig up a ton of the weird little scams and breakdowns and inefficiencies that support such caution. So many scams.
So much of the reason for mass immigration on the demand side is just demand to leech on the WERID social commons. Establish the argument that not all value held in a society is held privately on explicit property rights (open borders GMU economists are too autistic/dishonest to notice this). Societies involve a ton of socially-held common value that is only protected by relative stability and long-term enforcement of compatible customs. Mass immigration is the national equivalent of 1980s-style private equity trust liquidation. All the people here for that need to go back.
It's worth acknowledging the value of actual social diversity, meaning different endogenous subcultures living different ways dominating different parts of the economy etc. This is arguably one of the strengths of pre-20th century european society, and a major antidote to the monoculture-collapse that I would bet is coming in the 21st century. But this diversity must come from "inside the house" so to speak to be really balanced with the above social considerations. But this is maybe too theoretical and speculative to get into. Point being have some caution with Arctotherium's WEIRD-maximalism and gains-from-standardization arguments.
I agree with the other anon
>>3031 that you want to lead with the normal, well-implemented european social democracy version of remigration. That's what it should look like, so that's what should be emphasized. The argument is basically that as a proof of possibility and acceptability, and then a bunch of arguments for necessity that aren't ethnic particularist.
