Not at all.
America is a dystopian hellhole. Controlled entirely by the intelligence agencies, ultra rich people, corporate monopolies, the controlled press and the satanist.
If you have the impression that America is any remotely as you describe is because you have fallen victim of their own propaganda, which serves exactly the purpose to convince gullible foreign to migrate there and make them believe that American live style is nothing but the soulless nightmare it really is. This propaganda probably was developed to target people like the father of >>300290
. They saw that it was useful, and keep going until today. But now is hard to maintain that fake propaganda because many people can see how hellish America really is.
People who travel to that place lose their culture, their history and eventually their identity. Many people inside America have realised this and try to retake some of their heritage, that's the reason of the existence of so many in groups like British-american, Italian-american or whatever. But the power of that dystopian place is too great, its completely designed to make people lose as much identity as possible, because that is how the government, corporations and people who control the place want it. Easy to change, easy to manipulate.
It would be a net positive for the world, and even many people who live inside America if the dystopian system that exist there lose its influence over the world.
