I think that’s a bit oversimplified. Milei’s no doubt a knob and there’s a good chance he’ll screw up, but the alternative would have been the former minister of economy doing four years of the same, which would have been a 100% chance of screwing up. So before you make any more oversimplified statements, consider the alternative to Milei.
Milei has inherited a country on the brink of economic collapse and hyperinflation, caused by a government that has financed its overspending by just printing more money for decades, and borrowing whatever foreign currency it could. This is obviously not sustainable.
He wants to link the peso to the dollar (so the government can’t print more money at will anymore - not to mention the fact that many transactions are already half-legally done in dollars anyway) and do away with some of the many regulations that the Peronists have been promising for decades will help the economy, but which most experts agree have unsurprisingly crippled it further, and in many cases facilitated corruption.
His opponent’s political program can be summed up as “introduce more subsidies”.
Which one makes more sense to you?
