Publ,
Mao, the largest mass murdered in history tried the 'Great Leap Forward'. Apparently back yard steel mills don't work.
By the time Mao went room tempreture, he was responsible for the deaths of 60 to 70 million Chinese....more than Hitler and Stalin put together, maybe.
The final toll of China's current modernization efforts are yet to be told. The human, environmental and sociatal costs will be incalculable.
