China Super Rich Buying Planes and Yachts

I guess just recently there was some outcry over China citizens reckless driving especially on sports cars.   Now the super rich in China are engaging in yet another more expensive sports, that of having private jets or yachts.  These are many times more expensive than luxury cars and despite the 40% taxes, China had on such luxury goods, demand outpace supply.   I wonder how many super rich in China knows how many poor Chinese there are in their homeland?  Won't helping your fellow countrymen be better than trying to look for the most expensive plaything?
