Well... in my case I had little choice- my preferred country, Australia has become too expensive for me so I had to find somewhere that made my meager pension and savings go further. The argument that everywhere else is as costly as 'home' is false.
Originally my motivations were better prospects, warmer weather that cured my chest infections and a better future for my kids.  These are universal motivations, surely? Therefore I find some of the comments a bit wide of the mark. 
Besides that, I felt I had become a burden to my 'family' and this would get worse, meaning I'd be ever more dependent.   At 70 this was not an option. The ME age has been hard for most older people. So I live in exile, really- and I'm not alone in this.
