Mao's cultural revolution is what makes India and China different now. Cultural revolution completely removed class system in China and made everyone equal. A peasant can work to become a CEO of a large corporation and no one feel strange in China while India is still mired in caste systems. A peasant can work to challenge Western multinationals in China while this is unthinkable for people in India, Hong Kong and Taiwan. This is how China becomes the No. 1 manufacturing power because everyone in China believe that we can make it, and we can do it while people in other countries feel great if they can use western products.
Deng devalued Cultural revolution just wanted to prove that the coup in 1976 was valid. But after 1989, China has decided to let history judge cultural revolution. You rarely see official comments on Cultural revolution. Only proteges of Hu are still defaming cultural revolution. Cultural revolution mainly affected millions of intellectuals, those used to be top in Chinese classes, but Hu's one-child policy, minority policy and religion policy affected billions. Chinese people hate Hu's policies much more cultural revolution.
The growth of Chinese economy in 1980s was not as good as other stages. This was why the color revolution in 1989 happened. Chinese economy started to fly after 1992 when Deng wanted to balance both left and right.
