Inflation can come under control by April if nobody has a job or any money, so there's no demand, which is what I worry about happening.
Milei is an orthodox far right winger economically, so he's pursuing full austerity and hopes the invisible hand of the market™ does something (anyone remember Macri's lluvia de inversiones?) what that something is I have no idea, because as myself and others keep reminding people, every time this sort of "shock therapy" has been tried here or elsewhere, wages remain static at best, and shrink while costs rise.
I'm mostly concerned about social unrest as Quilmes said. If someone's salary remains $200/month and rent goes from $100 to $350 for a bachelor, meat doubles, rice/polenta/grains double, tomatoes have doubled, etc. then we're going to see an increase in insecurity and saqueos as desperate people do desperate things.
Nobody argues a change isn't/wasn't needed, it's the intensity, and the fact it's not falling on "the caste" that's the problem. Have you tried taking a bus lately? It's like waiting in line at ANSES, and we're not even in 2024 yet.
