Enver Hoxha talks about this in "The Khruschevites"
Here is his analysis of the symptoms:
<If a detailed analysis is made of the political, ideological and organizational directives of Stalin in the leadership and organization of the party, the war and the work, in general, mistakes of principle will not be found, but if we bear in mind how they were distorted by the enemies and applied in practice, we will see the dangerous consequences of these distortions and it will become obvious why the party began to become bureaucratic, to be immersed in routine work and dangerous formalism which sapped its strength and strangled its revolutionary spirit and enthusiasm. The party became covered by a heavy layer of rust, by political apathy, thinking mistakenly that the head, the leadership, operates and solves everything on its own. From such a concept, the situation was created that in every instance and about everything they would say, “this is the leadership’s business”, “the Central Committee does not make mistakes”, “Stalin has said this, and that’s all there is to it”, etc. Stalin might not have said many things, but they were covered with his name.
<The apparatus and the officials became “omnipotent”, “infallible” and operated in bureaucratic ways under the slogans of democratic centralism and bolshevik criticism and self-criticism, which were no longer bolshevik in reality.
<In such conditions bureaucratic administrative measures began to predominate over revolutionary measures. Vigilance was no longer operative because it was no longer revolutionary, regardless of all the boasting about it. From a vigilance of the party and the masses, it was being turned into a vigilance of bureaucratic apparatus and transformed, in fact, if not completely from the formal viewpoint, into a vigilance of the state security organs and the courts.
<It is understandable that in such conditions, non-proletarian, non-working class feelings and views began to take root and to be cultivated in the Communist Party of the Soviet Union and in the consciousness of many of the communists. Careerism, servility, charlatanism, unhealthy cronyism, anti-proletarian morality, etc., began to spread. These evils eroded the party from within, smothered the feeling of class struggle and sacrifice and encouraged seeking the “good life”, with comforts, with privileges, with personal gains and the least possible work and effort. In this way the bourgeois and petty-bourgeois mentality was created, and this was expressed in such words and thoughts as: “We worked and fought for this socialist state and we triumphed, now let us enjoy the benefits from it”, “we can’t be touched, the past excuses us for everything.” The greatest danger was that this outlook was becoming established even in the old cadres of the party with a splendid past and proletarian origin, even in the members of the Presidium of the Central Committee, who ought to have set an example of purity to the others. There were many such people in the leadership, in the apparatus, and they made adroit use of the revolutionary words and phrases and the theoretical formulas of Lenin and Stalin, reaped the laurels of the work of others and encouraged the bad example. Thus, a worker aristocracy made up of bureaucratic cadres was being created in the Communist Party of the Soviet Union.
<Regrettably, such a process of degeneration developed under the “joyful” and “hopeful” slogans that “everything is going well, normally, within the laws and norms of the party”, which in fact were being violated, that “the class struggle is still being waged”, that “democratic centralism is safeguarded”, “criticism and self-criticism continues as before”, that “there is steel unity in the party”, “there are no more factional, anti-party elements”, “the time of Trotskyite and Bukharinite groups is passed”, etc., etc. Generally speaking, even the revolutionary elements considered such a distorted concept of the situation to be a normal reality and, this is the essence of the drama and the fatal mistake, therefore, it was considered that there was nothing to be alarmed about, that the enemies, the thieves, the violators of morality were being condemned by the courts, that the unworthy members were being expelled from the party, and new members admitted to it, as usual, that the plans were being realized although there were some that were not being realized, that people were being criticized, condemned, praised, etc. Hence, according to them, life was proceeding normally, and thus it was reported to Stalin: “Everything is going normally.” We are convinced that if Stalin, as the great revolutionary he was, had known the reality of the situation in the party, he would have struck a crushing blow at this unhealthy spirit and the entire party and the Soviet people would have risen to their feet to support him because, quite correctly, they had great trust in Stalin.
