Sorry, it wasn't meant as a personal attack. I believe many people in 1st world nations do have selfish motives for maintaining the status quo but I fully accept that you may not be like that at all. I admit I went a bit overboard trying to get the debate going as I find people remarkably unwilling to discuss this topic.
my concerns (albeit potentially wrong) were more aimed at a town or cities ability school, house and possibly feed large influxes of people.
It all depends on what sort of people you are talking about. You already conceded that in developed nations with relatively wealthy people, such problems are minimal. After all, people will stop moving into an area if housing costs get to high, or conditions become unsatisfactory.
But what about poor people moving from poorer nations? Lets say they move to a large city in a first world nation and that city fails to school, house and possibly feed them. Where I come from (Zambia) a significant proportion of people are already not adequately schooled, housed or even fed. They would however mostly only move to a new country if conditions there were better than were they are now. So even if the conditions were not adequate by your standards, the end result is still better for the people. So your only remaining concern might be a lowering of standards for the current rich residents (hence my accusations of selfish protectionism).
i dont think there has ever been a situation in which the whole planet became border free, so we are in uncharted territory as to what exactly would happen in this hypothetical scenario.
Yet we have precedents with large countries/ regions such as the US, Europe and China and we can look at what happens there. After all, a quarter of the world lives in China and they have the largest migrations and great wealth disparities between regions. If the US or China instituted internal border controls, people would be up in arms about rights. Yet surprisingly, almost everyone seems to recognise without question the right of countries to maintain strict border controls.
