What model hindered the construction of democracy and legal system and the sustainable development of economy in the Soviet Union?

In fact, it is the corruption of the system! The Soviet government was openly corrupt and euphemistically called party building. This model is ignored by ordinary people. In addition, with the infiltration of western ideas, the United States drew a pie for the Soviet Union, and the people believed it and overthrew the regime of the CPSU. The Soviet model is to treat ordinary people as human beings. Ordinary people have no rights, no status and are bullied by officials. Western democracy is not what ordinary people need. Ordinary people don't want to participate in the discussion of state affairs, and they don't want any voting rights. What they need is civil rights, the right to speak and status. If they don't have the right to speak and status, giving them a few votes will also hinder the legal system construction and economic construction. What ordinary people want is someone to take care of them and have no worries. Western democracy cannot do this either.
