Very nice essay, comrade. It shows very clearly the Marxist-Leninist core of Deng Xiaoping's governance in contrast with late Mao's and Maoists' perception of him. I wanted to leave a few notes on some excerpts.
The first sentence is legitimate and it comes the work called 'To Uphold Socialism We Must Eliminate Poverty'. The 2nd sentence is not, however, and it contradicts what Deng Xiaoping stated
Apparently Deng did in fact say something like "To be rich is glorious". It is mentioned in an interview with Mike Wallace and Deng does not deny it. Instead, he expands on what he meant by that:
Wallace: To get rich is glorious. That declaration by Chinese leaders to their people surprises many in the capitalist world. What does that have to do with communism?
Deng: We went through the “cultural revolution”. During the “cultural revolution” there was a view that poor communism was preferable to rich capitalism. After I resumed office in the central leadership in 1974 and 1975, I criticized that view. Because I did so, I was brought down again. Of course, there were other reasons too. I said to them that there was no such thing as poor communism. According to Marxism, communist society is based on material abundance. Only when there is material abundance can the principle of a communist society — that is, “from each according to his ability, to each according to his needs” — be applied. Socialism is the first stage of communism. Of course, it covers a very long historical period. The main task in the socialist stage is to develop the productive forces, keep increasing the material wealth of society, steadily improve the life of the people and create material conditions for the advent of a communist society.
There can be no communism with pauperism, or socialism with pauperism. So to get rich is no sin. However, what we mean by getting rich is different from what you mean. Wealth in a socialist society belongs to the people. To get rich in a socialist society means prosperity for the entire people. The principles of socialism are: first, development of production and second, common prosperity. We permit some people and some regions to become prosperous first, for the purpose of achieving common prosperity faster. That is why our policy will not lead to polarization, to a situation where the rich get richer while the poor get poorer. To be frank, we shall not permit the emergence of a new bourgeoisie.
This same passage can be used to expand into the "After the Beginning of the Cultural Revolution" part, where you mention disputes between Deng and other tendencies
