It’s true. I was asking a person I know from Kenya what’s it’s like there. She said it’s a beautiful please, pretty good but I’d have to hire security guards to avoid getting kidnapped and ransomed. We just don’t realize how good the US is.
It's not that they're dumb, they're often simply unaware and misinformed. I had several international friends in college who studied in the US and almost all of them returned home. Many came to the US not just for education but intending to stay and do well for themselves. After dealing with the culture and environment here, most realized the places they came from weren't really all that bad and their opportunities there was just as good. Most assumed the US was NYC and LA everywhere.
This is clearly in contrast to people coming from poverty in say Sri Lanka where even the worst here are often doing better in terms of human rights, access to ERs, access to shelters, etc.
