In other words, the conversion of the Bolshevik party into a fully fledged "democratic centralist" party occurred during the degeneration of the Revolution. This was both a consequence of the rising authoritarianism within the party and society as well as one of its causes. As such, it is quite ironic that the model used by modern day followers of Lenin is that of the party during the decline of the revolution, not its peak. This is not surprising. Once in power, the Bolshevik party imposed a state capitalist regime onto the Russian people. Can it be surprising that the party structure which it developed to aid this process was also based on bourgeois attitudes and organisation? Simply put, the party model advocated by Lenin may not have been very effective during a revolution but it was exceedingly effective at prompting hierarchy and authority in the post-revolutionary regime. It simply replaced the old ruling elite with another, made up of members of the radical intelligentsia and odd ex-worker or ex-peasant.
This was due to the hierarchical and top-down nature of the party Lenin had created. While the party base was largely working class, the leadership was not. Full-time revolutionaries, they were either middle-class intellectuals or (occasionally) ex-workers and (even rarer) ex-peasants who had left their class to become part of the party machine. Even the delegates at the party congresses did not truly reflect class basis of the party membership. For example, the number of delegates was still dominated by white-collar or others (59.1% to 40.9%) at the sixth party congress at the end of July 1917. [Cliff, Lenin, vol. 2, p. 160] So while the party gathered more working class members in 1917, it cannot be said that this was reflected in the party leadership which remained dominated by non-working class elements. Rather than being a genuine working class organisation, the Bolshevik party was a hierarchical group headed by non-working class elements whose working class base could not effectively control them even during the revolution in 1917. It was only effective because these newly joined and radicalised working class members ignored their own party structure and its defining ideology.
