You know how lots of people want to immigrate to the US because it is better than where they come from? If you think Canada or one of the Scandinavian countries is better than where you are why don't you move to one of them?
If the nations of Scandinavia and Canada were truly so superior to the united states, millions of individuals would be seeking to immigrate to them through whatever means necessary and/or possible, rather than merely settling for the inferior standards of the united states. It is not even a question of distance, as millions have trekked across all of the nation of Mexico and beyond just to arrive at the border of the united states. Immigration numbers alien, illegal and otherwise, demonstrate the united states is the superior nation.
Per you it's modern, but as always you are incorrect, cease trying to change the US into other nations, if they are so good pack your butt up and move there, your anti American attitude is getting old and very boring.
Meaning that if the united states were to so-called "evolve" to the standards of the nation of Scandinavia, the borders would effectively be closed off to everyone, and all of the illegal aliens currently residing within would be forced to leave, as they would not be welcomed under any standard of law. To be like the nation of Scandinavia, the united states would have to become isolationist and xenophobic, to the point of forcing illegal aliens to die in the deserts of the nation of Mexico at the border.
