Yes, I think he's cherry-picking some specific situations to make it seem much more tragic that it was.
For instance,
> Some ate whatever they could; they hunted birds or ate street dogs and cats, others starved. When it comes to food, cities suck in a crisis.
Sure, some did. They even showed up on the news due to how weird even the idea of eating birds was. But that's the 0.001% - the average citizen reduced their expenses, moved back with their parents, asked their relatives for help, and/or started using the food banks.
> in 2001 half the country went without power for 3 days. Buenos Aires was one big dark grave.
That's straight up BS - there were widespread power outages, but they lasted typically hours, not days. And even though specific neighborhoods had days without power, to call it "a big dark grave" is too much.
> There are absolutely NO kids playing on the sidewalks at all, at any time of the day
There are no kids playing nowadays either, but that's because they are at school (the average school day is longer than it used to be), playing with their cellphones, or (at the time) playing Counter Strike in cyber-cafes with dedicated LANs.
And so on. It also doesn't help that he paints the entire country based on Buenos Aires, a city that has a very strong cultural division to the rest of the country.
