There is always a need for documentaries that boil down complicated financial dealings, but therein lay a fatal flaw, just the corruption on the US end, the bankers and brokers is complicated enough and we know and understand the culture that produced them.
The film makers have ommited a big disincentive for corrupt Chinese businessmen, and that is the tax department of the CCP. it may not be illegal to lie to foreign investors, but they are liable to pay a flat tax rate, if China wants to punish shady/embarassing businessmen. tax evasion lands many rich and poor in jail. the notion corruption is unchallenged is false.
Equally not mentioned is President Xi"s anti-corruption campaign. he is the most conservative leader since Mao, and is now President for life.
Just as the election of Trump vastly changed the financial regulations, so, too has Xi's election changed theirs.
