I was just responding to your assertion that poverty doesn't really exist in the United States. It's not as widespread as in Latin America, and tends to be more sporadic, but there are hundreds of thousands of people living in tents and improvised shelters with no access to running water or electricity and no hope for the future here. The United States is no more a homogeneous bloc of wealth and prosperity than Latin America is a continuous favela of poverty.
I read your core argument in this post to be that the form of poverty you describe is much more widespread in Latin America than in the United States. I'd be a fool to disagree with you on that. Yes, you're right.
I'm certainly not trying to win a pity contest and say that the United States is a horrible place where everything sucks. That would be absurd. But for many people, the United States is a much shittier place than you make it out to be.
As for the challenges of these places, they are daunting indeed. The United States is about as toxic a neighbor as one could ask for. Sending money and guns South, and bringing drugs North. Mounting coups. Stealing the best and the brightest from countries that desperately need that human capital. Putting children fleeing violence and poverty in cages. None of it should sit right with someone who has a modicum of conscience. But, as you have seen from our recent political battles, we barely know what to do to fix ourselves, let-alone help our neighbors. Our country is grappling with it's own reckoning as the rich get richer and the poor get poorer. Our Gini is 0.48 and growing. Mexico's is 0.5. With every passing year the homeless encampments get larger.
Perhaps the time will come when the fortunes are reversed?
