I happened on a documentary about this subject and China’s road to economic freedoms, Three high school students were shown random pictures, troops, a tank etc, nothing to form a pattern of an event and asked if these pictures meant anything to them. They all drew an honest blank and said no. Log on the internet and type in Tiananmen square and you get tourists and travel info. So much for Democracy, the young have no knowledge of this event. Shanghia a modern city is a far cry from the retched poor who live in the inner provinces. Once when everyone was dirt poor now some are rich and the majority are still poor leaves an incredible divide that will eventually come to the surface again but this time it could get real ugly!
