As a foreign "immigrant" (I put immigrant in quotes because I was just applying for graduate schools in a place known for good graduate schools, and more importantly, was getting paid in the process; never considered myself an immigrant because I felt, maybe naively, that I belonged equally here), I can unequivocally state that there are many things that make US an envy of the world, and why people like me want to come to US. The basic societal rules are the most important, and these are what make US great. The fact that there is, for the most part, essential equality in buying and selling, moving and settling, working and playing, being treated about the same regardless of how you look or talk, form own cultural/religious circles, shout on streets and stand for elections, etc. is very very very important. Even in the smallest of towns, there is essential camaraderie after a brief hesitation by the majority of people. There is relatively lot less exclusivity and exclusion. Only in US can you be very different, form your own circle of difference, and everyone will just let you be. For example, even though my ancestors have been in southern India for thousands of years, if I say or write a text that the government thinks is critical of them, they will throw my Muslim ass in jail without any recourse.
Even the most liberal of western European countries do not tolerate, let alone celebrate diversity as US does, except of those "diverse" aspects that they have decided are part of their identity. Then they are not really diverse, is it? No country gives the same platform to so much diversity as this country. Of course, this country has the slavery history that it weaned out from in fits and starts, and continues to marginalize the Black community systematically. As an "immigrant", I owe my life experience in the US to the sacrifices of the Black community. They have paid and continue to pay a heavy price so that we can be doctors and CEOs.
I get Brisket's points, but his observations are not unique to US, but more a state of the world. Show me a place where intolerance, authoritarianism and inequity isn't on the rise. Whether the rich (US, east/west Europe, Australia, Israel), middle (Turkey, Saudi, Brazil, China, Russia), poor (India, Iran, Egypt) or insignificant (Myanmar, Sri Lanka, most of the Arab countries, central Asian *stans, Balkans, central America, sub-Saharan Africa), the world is hurtling towards organized fleecing and populist vigilantism. Ironically, the only country that is slightly limping in the other direction is Pakistan. Their PM is a good guy, but of course all the surrounding goons (Modi, MBS, Netanyahu) hate him. If he cannot survive for long, they will fall back to military rule.
tl;dr: I agree with Brisket's gloom, but it is worldwide, and US is still the best of the lot.
