The chart you listed is for the years before the CCP won the civil war in 1949. But agreed that many of the problems overcome were also problems that were created after the war.
Japan controlled much more of China than the communists did before 1945. And having half your country occupied is bad for GDP. You made a mistake and believed some propaganda here.
Chinese GDP was higher during WWII than over the next several years, the actual minimum 1959 to 1961 was well into communist rule. Literally CCP rule was worse than the anarchy of civically war, it’s right up there with the insanity of Pol Pot.
This so historically stupid claim, it's not even wrong tier.
There was no GDP data under KMT - it wasn't even formally calculated.
CCP started GDP calculations, but using soviet MPS GDP accounting system that basically omitted services and lowballed production prices.
The only GDP data we have that is pseudo normalized are via estimates like Maddison project. Even they don't bother to recompose China/KMT data during WW2. The TLDR is prewar peak 1939 data (right before JP invasion) around 288B, PRC took over in 1949, GDP was 245B in 1950, grew to 306B by 1952. GLF tanked GDP from 460b to 350B... i.e. the worst case scenario of GLF floor was still 40% larger than 1950.
E: Note wiki data links to ourworldindata that pulls from Maddison and in table form KMT/WW2 data is not available and only pulling from closest data point 1938/1950 and naively extrapolating per capita. Because KMT data doesn't exist.
Did China really do it though? We can clearly see that China has achieved huge economic growth since Deng Xiaoping took control. But the specific numbers can't be attempted to be believed. Communist Party officials at every level heavily manipulate the official economic data to meet their annual goals and no independent auditing is allowed.
By pulling ten million people a year from farms into factories and ploughing 40% of GDP into infrastructure and education. Sounds like a sound analogy to me.
They're for those within the population that are willing to submit themselves to the whim of the state and whose prosperity in some way directly benefits the oligarchs that run the state.
Certainly, as just a few examples, they are not for the well-being of the Uyghar population or pro-democracy activists or journalists investigating human rights violation or supporters of Tibetan independence.
Developed countries have slow growth because they need to invent the improvements not just copy what works from other countries.
