People will only keep immigrating until the average quality of life is the same in the UK as it is anywhere else; then there will be an equilibrium.

That quality will be substantially less than it is in the UK right now. That is why the current population of the UK, and any other developed country (i.e. any country with a standard of living much higher than the world average), does not want unrestricted immigration.

Yes, of course. But the net average quality of life is increased overall. Please examine the posts that I'm replying to here, for the context of the point I am making. For convenience I've copied it below:

How many billion people would be better off if allowed to immigrate to GB? Utilitarianism is about counting everyone's utility the same...

You can't fit billions of people in the UK.

If you are entering the argument with a claim that the UK's current inhabitants can be utilitarian and simultaneously weigh their own utility higher than those of other humans, then you should be directing your argument toward buybuydanddavis' post, since ze's the one who said "That weighting factor should be 1 for all". I am merely noting that not being able to fit billions of people in the UK is not a valid counterargument; net utility will still be increased by such a policy no matter what the UK's population carrying capacity is.

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.

But the net average quality of life is increased overall.

If that is an argument for doing it, it's also an argument for managing one's own home the same way. That ended badly for George Price.

I don't recognise an obligation to give my stuff away so long as anyone has less than I do, and I take the same attitude at every scale. There's nothing wrong with anyone trying to emigrate to a better place than they are in; but nothing wrong with No Entry signs either.

That's fine. Do you consider yourself a utilitarian? Many people do not.

For that matter, following Illano's line of thought, it's not clear that the amount that poor people would appreciate receiving all of my possessions is greater than the amount of sadness I would suffer from losing everything I own. (Although if I was giving it away out of a feeling of moral inclination to do so, I would presumably be happy with my choice). I'm not sure what George Price was thinking exactly.

No, I don't. The Price endgame is one reason why. The complexity of value is another. I do what seems good to me. That may be informed by theorising, but cannot be subservient to it.
