Earlier quoted context omitted.
Have you seen the poorer parts of the United States? Or walked around the Tenderloin? Or seen what meth has done to parts of the rust belt, and the farming communities that have been hollowed out and eviscerated across the midwest? Ever been to a reservation?
you are comparing a marginalized demographic against people who belong to the middle class on Latin America. it's totally out of sense. we also have cracolandia and favelas and people dying of diarrhoea and dying of hunger in some regions. please, don't visit a country with probably tourist type of visit and sum up a whole continent on socioeconomics or whatever category your empirical sociologic observation was edit…
That said, I'd rather live in middle lower class Latin America that Estados Unidos any day. The food is probably going to be better - too many places in the States Walmart is the only practical option now - health care won't bankrupt you, and people in Latin America are almost universally better educated and less depressed on social issues.
And I think a lot of that can be traced to a culture that's a bit less authoritarian, because people understand the history of why that doesn't work. Just going to war with the Mafia or the narcos is a trite answer, but it usually doesn't solve things in the long run.
Edit - also, you really should compare the poorer parts of the big cities you're talking about to Detroit or New Orleans or the Tenderloin. In my experience, people in Latin America can also have a skewed perspective. The world is a big place.
