In times past and in other cultures, someone might migrate solo and later bring their family over. I've read stories of European migrants doing this to Australia. Sometimes, it would be years later. Were people then more willing to leave partners or kids behind? Or elderly parents? I don't think I'd ever entertain the idea of moving without my partner and children like that. Even in a very connected world, my partner is not interested in being away from her circle of friends for any serious length of time, let alone a major career/lifestyle move.
