The truth is that patriotism is ridiculous, it's just culture plus racism. IMHO your 'question' is thinly veiled racism.
I want the place where I have chosen to live to be prosperous, because I think prosperity helps to generate a better quality of life for me and my neighbors.
.......then that suggests that my home neighborhood is on the decline relative those places.
Fair enough. I don't disagree with anything you said. As you say, that's one way to look at it.
My way of looking at it is: "I want the place
where I happen to live to be prosperous, because I think prosperity helps to generate a better quality of life for me and my neighbors.
Since I happen to live on earth, I'm not concerned with one particular "home" country, state, city, or neighborhood staying prosperous as much as I as I am seeing prosperity increase for as much of humanity as possible.
I live in a nice neighborhood in the United States. By global standards, everyone in my hood is rich. I recognize that if prosperity around the globe increases significantly, my current neighborhood will likely decline in prosperity relative to the rest of the world. And I wouldn't wish for anything less. Of course "relative" is the key word. Because if everyone living in poverty around the world became just enough more prosperous to live with basic human needs my neighborhood would naturally become
relatively less prosperous when compared to those folks... since their circumstances improved greatly.
Of course the word prosperous has a great deal of "relativity" built in because it compares the standard of living for one to that of the rest. Since I'm concerned with increasing prosperity for as much of humanity as possible, that necessarily means that I'm concerned with decreasing the (relative) prosperity of others, including myself. Yes, I'm perfectly content to maintain my current standard of living, but lose my status of being rich by global standards. Nothing would make me happier. Even if it meant Chinese or Cambodians could afford to live in my hood!!
