This is what boggles my mind, if you're a far right guy why would you chose Argentina of all places, thinking it is more libertarian than the US? You do realize the Argentine state is still prosecuting people that broke quarantine, and we had one of the longest lockdowns in the world, right? We also have tons of migrants (and you'd be one too, or did you only mean to call brown people migrants?), and Argentina is not gun friendly, so again, not sure where you're getting these ideas from, because Chile is much closer to what you're thinking of, but it's also more "ethnic" which you may not like
I agree that there will be far fewer. Argentina is going to be more expensive. If Milei is elected there will be economic reforms, even if dollarisation is deferred. For those who have dollars it will be mostly cheaper than North America or Europe but I expect salaries to become more competitive with the rest of Latin America. The country can't go on with the majority earning u$s 200 or less a month. Argentina will become a less appealing destination for those who do not have a serious commitment to the country.
He seems to be thinking that Milei will be elected and that the country will turn conservative but even if Milei is elected Milei's philosophy is not really conservative in the US sense. You are correct of course that Argentina has been left leaning for a long time. Chile used to be conservative but that has changed, no?
