That's a pretty shitty solution for everyone involved if they don't actually
want to be separated from the rest of their family by 3,000 miles. And not just their families, but their friends and communities, which have a profound impact on overall well-being in their later years.
I wouldn't call your suggestion deliberately cruel since you don't seem to have any idea how socially damaging this kind of isolating displacement can be. But I would say that the forced separation of people from their famalies and communities is a really hideous policy outcome, and one that should be strenuously avoided.
Obviously, if somebody wants to move far away, fine. But forcing them to do so is horribly wrong.
