Slowly? America is just been America, this is who they are right from the beginning, they should have become the enemy of the world already, but I guess it just doesn't matter.
I can't survive in America, this is just me, my country people believe that America is the best in the world, you get job and you live a good life but that's not so true, they have their own disadvantages too.
Guns are free and can be owned by anyone, you can get shot at any time, taxes are killing, you have to work your ass to stupor to survive unless you have some good skills or degree, such world isn't just for me.
The only problem in my country is insecurity, but I will rather struggle here and survive or get killed than living in a country where I don't belong originally.
If it was that easy, then there wouldn't be tens of thousands, in fact over hundreds of thousands of people all over USA as a nation, people on the streets dying off drugs. Moreover, they are not happy to be there either. But if you are coming from a nation with a minimum wage of 100 dollars per month, going to a nation with nearly 10 bucks per hour, becomes suddenly better and you are happier because you saw economically worse situations, so you want to do better here.
And to be fair, if you ignore the healthcare problem that they are facing, rest are economically fine compared to many many poor nations. I rather be in most of Europe than USA, but I would rather be in the USA than most of the poor nations.
