Is there a country in South America that's an example of the pinnacle of
any system?
I mean, you can rant and rave about how socialism failed Venezuela, but can you then point to a country in South America where unfettered capitalism has just been the bee's knees? Because there seem to be a great number of places where small, ineffectual governments have basically let the major monetary powers (usually drug-related) run slipshod over entire countries. Seems the "free hand of the market" proved fairly ineffective in allowing people the economic means to overcome murderous drug cartels.
Most of South America is all shades of the same spectrum. Largely impoverished, corrupt, or generally lacking in economic infrastructure. Singling out Venezuela is a hollow soap boxing point.
I mean you could look at
Bolivia, which has taken socialist measures since the mid-2000s and has actually reduced their poverty rate by 11% in 5 years, but, hey, that doesn't fit the narrative, so... why do that?
No one expects anyone to look at the bigger picture.
