What do you believe Socialism and Communism looks like? Where is the line between the “administration of things” as Engels describes it, and a state acting as proxy? You keep saying workers didn’t have control, but by all accounts they did, and the material benefits prove this. You may want to read Soviet Democracy and Is the Red Flag Flying? Political Economy of the Soviet Union. The Material improvements are a symptom of the system at work, not proof of it but support the thesis. You have nothing supporting your thesis.

Dialectical analysis is important, yes, but just calling your analysis dialectical even if it stands in contrast with reality and the social knowledge of hundreds of millions of Marxists requires serious burden of proof. Marxism-Leninism is a science because it evolves, but simply going against the grain without materialist analysis doesn’t mean you have a point.
