But the net average quality of life is increased overall.
I’m not sure this necessarily holds true. In very broad strokes, if the quality of life is increased by X for a single immigrant, but having that immigrant present in the country decreases the quality of life for the existing population by more than X/population, then even if a specific immigrants quality of life is improved, it doesn’t mean that the net average quality of life is increased overall.
Yes..… you may be right, and it is a compelling reason, for example, not to admit terrorists into a country.
I suppose that if a particular individual’s admission into the country would depress the entire country by a sufficient amount, then that’s a fair reason to keep them out, without worrying about valuing different peoples’ utilities unequally.
