Argentinians already do everything possible to get paid in dollars, so they might as well make it their official currency, assuming that doesn't have any negative consequences for the dollar overall. I know some people who live in Argentina and they said that if they got paid in pesos, their paycheck would be worthless within a few days. If they don't get paid in dollars then they have to pay fees to convert pesos to dollars for any money they're not going to immediately spend, and there's a very small limit on how much they can convert at a time. It sounds like a really fucked up financial situation over there. On top of all of that, they're facing a housing price crisis, just like the rest of the world.
