@georgia I don't read enough history books to understand what you're saying.

I would disagree with categorizing party officials as a class, it's more of a problem of division of labor.
At least as far the GDR goes the "party bourgeois" lie was always a completely baseless western psyop. The productive means was always in service of the centralized production for popular consumption, there was indeed progress in de-commodification of goods and few options for bureaucrats to use common productive means for personal gain. Even higher party officials had a quality of life that would be just middle class in bourgeois societies, while there was no objective poverty at all with general working people.
In orthodox interpretations of marx division of labor is a bourgeois phenomenon, in further progressions of socialism common factory workers and agricultural workers are required to have a sufficient intellectual foundation to engage with higher theory, literature and art. Even there the GDR somewhat succeeded, working class authors and musicians meaningfully shaping general literature and art basically don't exist anymore in germany, it's all middle class circlejerk.
So you can say historical socialism had insufficient progress in abolishing labor division, but a collective class of bureaucrats still didn't really exist (maybe in the later revisionist soviet union, but that was leaning more into autocratic social democracy anyway).
