I'm from Peru and it is a relief to see that politics are starting to swing back right in South America. He is cleaning house and facing a lot of pushback, Argentina has been so subsidized that there is sticker shock on everything, as his plan eliminated a lot of useless subsidies and is now truing the actual cost of living. Almost half of Argentinians lived off the government in some way, and they feared he would (as he did) fire them, so they would rather live in bureaucracy and let the country rot.
Corruption is rampant so uopefully he is able to continue doing what he has done so far, and show that there is indeed a light at the end of the tunnel and other countries follow suit.
