To be fair, it's winter break now. Just because people line up to spend money on a theme park doesn't mean they're flush with cash. Me, I'm poor, but I'll still buy myself a luxury once and again and then scrape by on fumes for a few months...just to feel alive in this economic minefield the world's oligarchies are creating for folks. You can also think of it this way...as it's winter break, maybe those families going to a Tigre amusement park would have traveled instead, but now can't afford it...so they line up to go on a few rollercoasters. I don't think we can say the state of the economy is booming for folks and erase how it's knocked a lot of people into unstable territory. Argentina has always been a country that spends what little they have like they won't have it tomorrow, precisely because the politicians create these ongoing economic messes.
People here celebrate a blue sky, a mild and temperate morning. They don't save for a rainy day, they've learned better. So, even when people are suffering financially, you'll still see them out to eat, taking advantage of the cultural centers and accessible museums, parks, recreation. There are also still rich people here that have reserves and spend them. I think the fuller picture would account for how many people are struggling right now, while also realizing there's a large portion of the population who make good wages and can afford even more luxury, and even more of the population who are tight on funds but refuse to allow themselves to be cast out of life completely (so they spend anyway and skimp where they can to make up for it). Income inequality exists everyplace. It exists here, most certainly.
I love this country precisely because even the 'have nots' like to throw the future to the breeze sometimes to place their bets on a steak dinner, a quart of ice cream, a bottle of wine. And that's not as frowned upon here as in the States...where if someone making less than $100,000/year buys an avocado toast or a take-away coffee to brighten the bleak future ahead, they're seen as irresponsible villains of their own stories (nevermind the policies in place to make a slice of bread with half an avocado spread atop it $25 in the first place).
It's good to know fun can still be had by so many, I hope it continues on that way and that one day this country is run by folks who truly care to enrich the population writ large, in whole (not in part). A Christmas miracle that would be.
