The richest people on this earth did not get there by making stupid investments
Sorry GEH if I misunderstood but are you referring to the Chinese when you say the richest people on earth ?
With a meagre 2 in the top 100 richest in the world list ( 1 at no10 and 1 at no37 ) and both of them Hong Kongers, I would suggest that with nearly 20% of the worlds population, the mainlanders are not that bright.
As for hainan, the so called " cashed up " largest private airline in China had to get a 500,000,000 handout from the Chinese gov during the GFC so they did'nt go under, so not too sure how bright they are either.
