This is of course extremely biased meme. The reality is that so far Milei achieved a lot of what he planned for. The main issue in Argentina was huge inflation and out of control public spending. Both ruling parties were unable to address this for years so people got fed up and elected Milei as a kind of protest leader ("politicians can't help us so fuck it, let the whole thing just collapse"). Just how tired of constant economic crisis running for decades everyone was is another story.
So Milei won and did what the previous governments didn't want to do: cut spending. He got inflation under control by sacrificing big chunks of society. Old people got screwed, poor people got screwed but so far his plan of "short time suffering to achieve long term stability" seems to be working. Inflation is down, poverty is down, foreign investment and trade looks good. The question is no longer if Milei's reforms will collapse the economy or not (they didn't) but if the reforms will work long term or if the improvements will be short lived and not worth all the suffering it caused.
Like most people here I hoped that Milei's politics will explode in his face and we'll have a clear proof that the ideas sold by right wing populists are bullshit but it didn't happen. The jury is still out on Argentina but anyway, each country is different and even if it will work there long term it doesn't mean guys with crazy hair are good for the economy (as we can see globally now).
