I shall quote:

“ The right of workers to manage the state, the military, various enterprises, and cultural and educational affairs is, in fact, the greatest and most fundamental right of workers under the socialist system. Without this right, other rights of workers—such as the right to work, the right to rest, and the right to education—cannot be guaranteed. … We must not understand the issue of the people's rights as meaning that the state is managed only by a small group of people, while the rest of the people merely enjoy rights such as labor, education, and social security under their management.”

Meaningless. You can replace socialist by capitalist and it would be equally meaningless.

The correct word is democracy. The people (or "workers") having a say or not has nothing to do with socialism or capitalism IMO.
