Koreans can do it because they live in a country where laws and rules are enforced and the young soccer hopefuls advance to the next level based on personal merits.if the Koreans can do it I cannot see why Chinese cannot do it or better.
Chinese cannot do it because they live in a lawless country where soccer hopefuls advance based on the amount of bribery paid to the coach for recommendations and personal connection to government/sports officials.
So China's Leo Mesi is probably a poor farmer's son or a non-Han Chinese ethnic minority who shows an incredible potential at elementary/middle school, but doesn't have the money to pay off his coach, could not advance to high school or college soccer program, and end up farming or at Foxcon's factory floor, while some high ranking communist party official's spoiled and untalented son makes it to China's WorldCup/Olympic soccer squad thanks to his dad/uncle, only to humiliate China again and again.
