We could be like Canada or Australia, but instead of a british colony we were filled with spanish and italians and here we are
Seriously, yes, the country's economy has been a mess for the last 80 years as we still depend on agro exportations like a century ago while the world has moved on. And we had every type of government. Leftist, right and center peronists, weak non peronists center right and center left, military coups from every corner, and all helped to build this mess. So, in theory, a far right libertarian could be a good gamble as we have nothing to lose, right?
The little problem is the man is a madman sorrounded by freaks, that even if his economic ideas have some grounds, are almost impossible to follow given the state of power (and also the Constitution!), and let's not start with the social and cultural ideas and projects like breaking ties with "communist" states like Brazil (?) and also the Vatican (!), free posession of guns, to sell organs freely and even children (there's no way they can be approved, though, but just that people can think about it is a bit scary).
We may be in a constant economic crisis that makes the country weaker and weaker in every aspect (except football ), but a lot of people still value the social standards of living, like public access to education or health, conservative issues like family and catholic values, and it seems we are still not desperate enough to give the keys to a Trump style guy who wants to turn everything upside down. But we'll see.
