Why is emigrating from the US considered such a radical thing to do? Why does it dismay or even infuriate so many people that an American would consider leaving?
We readily accept people moving to the US from just about anywhere else. No one thinks immigrants have deserted or abandoned Russia, India, Ireland or the Dominican Republic. (No Americans, anyway.)
That must be a clue. We think of the US as someplace people move to, in search of a better life. We grow up hearing that the US is the greatest country in the world - and so many Americans believe it. The idea that anyplace could actually be better is simply unthinkable.
Guess what? People also emigrate to Canada - in droves. They come from all over the world, looking for the same things as immigrants to the US, plus greater tolerance, the guarantee of health care, a burgeoning economy that welcomes immigrants, and a generally more humane way of life.
