What, you think he's wrong because China had a bad economic quarter two years after he posted that? You realize China has had unprecedented growth over the past 15 years, with pundits predicting its collapse the entire time. They have 1.4B people, a very good education system, and a huge head of steam.

China misses GDP targets by 1% for a single quarter, every news outlet reports on it, and in five years everyone is going to wonder how China has gotten to the place it has. That's basically happened repeatedly over the past 15-20 years.
