That's what I call the Argentina syndrome...In the first half of the 20th Century Argentina's standard of living was in the tops of the world, but then a series of military coups and other problems caused major disruptions and they never really recovered.
Yes, when Peron took power, Argentina's per capita income was sixth in the world. WHile he was a military man, the country's economic crash was more on account of his lunge for socialism, almost to the level of Russia's "Great Experiment". It can take generations to recover from the disease. Compare what is now happening to Venezuela. Any improvement to the peasants will be temporary as production from all sectors, certainly including agriculture, continue their sharp decline.
Didn't Juan Peron die in 1974?  The Argentine collapse wasn't until the late 90s with a lot of poor leadership in between.

I'm quite optimistic about Venezuela's chances.  They might very end up in better shape than the US - at least those who don't spend their money on second homes in Florida.

Peron was in power from 1946 to 1955, nine years, and it was wholly after the collapse of wheat prices caused by artificial fertilisers and crop mechanisation had destroyed Argentina's market position.
But he was the only populist they could blame things on, so he got the blame.
