Not sure how you figure I have an axe to grind against those with money - fair to say I have an axe to grind against those who think the world revolves around them and overstate their importance, wherever and whoever they may be. You don't need to be entitled to be rich.
If the described group of people who want so desperately to travel (and most importantly actually do travel) during the COVID pandemic, and really do make up the mass of mass tourism then simply put, where are they? (Not here in Argentina obviously, but in the locations which they have had access to all along - like Mexico who continues to achieve barely 40% hotel occupation since COVID or airlines who can't even fill flights forcing them to axe and continue to reduce capacity even between and within unrestricted markets? How can Argentine hope to be any different especially when it is further from these markets and pre-covid had much smaller inbounds from these markets compared to Mexico/ Carribbean?)
Assuming everyone who has money is travelling and will travel is ludicrous. Assuming that the described demographic make up a chunk of the numbers needed to get meaningful economic benefit in an industry designed around far larger volumes is equally ludicrous - it is like saying "my $10,000 is worth more than the $100,000,000 everyone else and my $10,000 is going to save some third world country." It is not and it will not, hence don't be shocked when there is not a red carpet welcome tailor made for you. Brazilian tourists on the other hand, now there is a meaningful volume that adds up to a more meaningful amount, at least in the eyes of this government. Hence this stupid and non-sensical policy.
Sometimes people need a reminder if they are but a drop in the ocean or the ocean itself when asking things "why can't I do what I want right now" - governments (in this country anyway) like airlines, like tourism industries, tend to think more about oceans than drops.
