As the other commenter put it, it depends on how it's structured. There are so many ways to set up a coop I won't get into how shares affect dividends. Instead I'll use your example to show why your voting right is worth more than how the profits gets distributed.
If you're making ten bucks from your share and the founder is making a million, then the cooperative has to be okay with that arrangement. If you're collectively not okay with it then you have the power to change that. The founder can have all the shares in the world, they still have one vote. Since you collectively have the majority of votes you can simply vote to change how profits get distributed and the founder has to accept it because they don't own the cooperative, you all do.
As someone also from a post soviet country, don't make the mistake of thinking all socialism is the same as Leninism.
So you'd rather support a system where the power is handed to the unelected "officials"? You can see that happening in real time with Musk effectively leading the US. Not to mention almost all forms of democracy have people handing the power to the elected government, so I really don't know what you're opposing here.
