Well, the thing wagwang's parents did that improved the well-being of the people after them was to leave China.

What the Chinese society had been collectively doing for the previous ten years, however, was creating "the deadliest famine and one of the greatest man-made disasters in human history, with an estimated death toll due to starvation that ranges in the tens of millions (15 to 55 million)." And the following ten years included the first six years of the Cultural Revolution:

> Estimates of the death toll vary widely, typically ranging from 1–2 million, including a massacre in Guangxi that included acts of cannibalism, as well as massacres in Beijing, Inner Mongolia, Guangdong, Yunnan, and Hunan. Red Guards sought to destroy the Four Olds (old ideas, old culture, old customs, and old habits), which often took the form of destroying historical artifacts and cultural and religious sites. Tens of millions were persecuted, including senior officials such as Liu Shaoqi, Deng Xiaoping and Peng Dehuai; millions were persecuted for being members of the Five Black Categories, with intellectuals and scientists labelled as the Stinking Old Ninth. The country's schools and universities were closed, and the National College Entrance Examinations were cancelled.

I don't think any of that can be accurately described as "everybody else doing unpleasant things for a while to improve the well-being of everyone after them."

Chinese history, including in the 20th century, includes many of the brightest stars that have ever illuminated human history, and after the Cultural Revolution, a meteoric rise out of poverty, led by the same Deng Xiaoping whose son was tortured and crippled by Red Guards in the Cultural Revolution. But specifically in 01962 "everybody" was creating that poverty and worsening the well-being of everyone after them.
