Not really that interesting. Do they have any info on the number of argentines working on wall st who don't return vs other nationalities? I know plenty of argentines here who've worked abroad and come back and Im sure plenty of Colombians etc are perms any emigrants.
As opposed to non-Argentines who enjoy greater professional success in countries that reward consensus within the group?
Let's ask HybridAmbassador....
but seriously without even going to Japan... what other nationality are you thinking of?
Swedes do real well in business outside Sweden (and even within Sweden but that's another story)
