They exist, friends dad hates the uk with every fibre in his being, him & the wife were born there. They've also lived in oz, their kids moved to nz a few years back and they went over for a long stay (retired) to check it out with the aim of joining the children & grandkids (which would be easy as they're oz citizens), old guy said notta fsck he's gonna spend his last years in sa as nz is not for him. These are well-off people with za, oz, uk & irish citizenship that can pick where they wanna live. That said they're 'glad' their children left for their future.
I also know a few europeans that wont go back (one has royal blood nogals, lol).
