Get history books and read a bit. All you describe happened many times before. Nothing new here. You want currency crises? Read about Roman Empire dude. Oh wait, the red shield was already there scripting lives and controlling people. Oh guess what, they opened borders too, and emigrants flooded in, the empire collapsed.
Does this mean that USA will collapse one day too? Is it a natural way of things, natural way for people to screw up things, or someone have to control and arrange that. lol, don't give people to much credit. They barely can control their own lives, and you require them to control others. And what for, extra work? They are rich already.
