Dunno. If you can't get your act together where you come from (excluding war, famine, drought etc., and most certainly in developed countries) chances are you'll be even worse off in a strange place where you don't even speak the language. You always take yourself with you.
Takes a fair level of drive, grit and ability to set up in another country at any age or stage of life. Those with no roof and using deleted buckets usually don't possess those characteristics. (Without being judgmental about that fact.)
