Great point! When typing my reply I actually wasn't sure about using 'developed countries' as the term, but it was the one that came to me fastest. In a discussion further down the thread I just called it 'country of origin', maybe using something like that would have been more fitting.
Let's say you have the potential to be a great cricketer, but you're born in a country where cricket is not even played.
You're SOL.
Or you (the great cricketer) could be born in India and be a millionaire by 20.
