Why would anyone choose to be an American?
Because perception of your country or another country is more important (and always will be) than real facts.
I’m regularly asked by strangers and my Malaysian in-laws, “why don’t you love America? It’s the greatest place in the world!” The belief that any place is better than your own place (company, partner, home, country, etc) is a mix of perception and personal experience. Factual realities have little influence.
