Here's what you can hear about the USA.
1)Endless suburban sprawl, resulting in massive environmental destruction. Illegal immigrants heavily involved in the construction industry, leading to mass exploitation
2)Structural racism
3)Human rights on a sliding scale, with rich white rapists getting no jail sentences, and poor black people and immigrants going to jail for minor offenses.
4)Rich consumers pushing environmental and human rights issues to poor countries where people are exploited to build your $1000 phone and $250 shoe.
5)Lots of places where if you go and say "I'm an Atheist, Jesus is not God" will likely result in violence against you
6)Corrupt legal system, heavily favoring corporations and rich people
7)Absurdly hot in parts of it, Absurdly cold in other parts of it.
>I can't believe anyone would voluntarily go there, seems like hell on earth.
Lots of people probably feel that way about the USA based on the news.
UAE (Dubai, Abu Dhabi), and other countries in that region, have a lot of issues. I'll be the first to admit it having had second class status there. But I can't help but feel that a lot of Western news outlets love to bash that part of the world because it plays into how a lot of people like to feel like the rest of the world is a shithole.
This is not the case in the Arab world, for example. I grew up there and have seen horrors of which there is no documented evidence.
You are correct - despite all its flaws, the USA remains a magnet for talent from around the world.
