And everyone else from that country is worthless?
There is a difference between an exception and a rule. Just because Micheal Jordan won six championships doesn't mean I failed to do so because I didn't try hard enough at basketball over the years. I put in the time and effort, but the ceiling wasn't there. So did millions of others who didn't become Michael Jordan despite their best efforts.
Pointing out any deviation from the norm, while a great story and commendable effort on the part of the parties involved, does nothing to address the larger issue of societal change. You can't extrapolate one example as the blueprint for everyone.
Protip: He is indicating to you that there is no rule.
