Lol, what an absurd interpretation of the data, and accusing me of moving goal posts when all I did was pointing out that the data doesn't fit to your warped story.
And 1965 to 1970 was the hight of the cultural revolution, meaning the communist party was mostly engulfed in an internal power struggle, which left the people in China mostly to their own devices (and not actively damaged by earlier disasterous policies by Mao, like the great leap forward), and in 1970 to 1975 the reformist around Deng already started getting the upper hand in actual implementation and the result is the state-capitalist country we know today ("communism", lol 🤦).
And I explicitly stated that I do not defend the military dictatorship in SK. I only pointed out that your beloved Maoists in China somehow did significantly worse than them until China started adopting similar policies in the 1970ties. Literally doing nothing would have been the better strategy for the Chinese government, as the 1965 to 1970 data clearly shows.
P.S.: The Phillipines seem to also have somewhat outperformed China on that metric in the 1950ties (at least they didn't do worse), but were later held back by the Marcos regime: https://www.statista.com/statistics/1072232/life-expectancy-philippines-historical/
P.P.S.: Indonesia also doesn't show a Mao induced delay in the raise of life expectancy: https://www.statista.com/statistics/1072197/life-expectancy-indonesia-historical/
