This depends on who you ask of course.
Those that stood on the receiving side of collectivism will complain a lot when the bribe for their complience with the system shuts down. And if you squeeze those that pay for it, then they will complain and give up in increasing numbers.
I hate collectivism.
It also depends on what time period you choose. And what data you consider relevant. You can cherry pick to proove almost any point you like.
I can only say I like the steps that Milei took that made the state smaller. Devil is in the detail though and I expect (at least) some of the privatization efforts were just powergrabs by cronies.
Lula is a big state authoritarian, I never heard of any deregulation nor any other step that he took to make the state power smaller. The same goes to Trump and all EU "leaders" as well. Not to pick on just one collectivist when he's just one of many.
