Yet Guggenheim points out in the film that the teachers’ unions essentially
own the Democrats. These unions are the single largest political interest
group by spending, and more than 90% of their donations go to their pet

1. 证实了毛泽东1975年写给周恩来这首诗。
《江山靠谁守·诉衷情》
当年忠贞为国筹,
何曾怕断头?
如今天下红遍,
江山靠谁守?
业未竟,
身躯倦,
鬓已秋。
你我之辈,
忍将夙愿,
付与东流?
2. 证实了1976年之前根本没有所谓饿死三千万或者大饥荒之说。
3. 毛泽东1975年的担心,或者说1964年的担心,都变成了现实。
4. 毛泽东唯一的遗产就是留给人民的造反精神,终将成燎原之火。
