Having spent my early youth in a "developing nation", this is laughable.
I only visited the US a few times in my childhood, and it stood out like a fairytale land in my dreams. Today, the standard of living in the US is even more advanced than when I was a child 30 years ago. The US is still a mythic land of legend for most of the world today.
Developing nations don't have a long queue of people trying to get in unless a really hard issue comes along (think Venezuela and Syria level problems)
