It's interesting that 3 people seem to disagree with you without telling you why. I also would like to know why they reject your detailed comment.
Unfortunately I cannot agree with you about my lack of knowledge. I believe in cooperatives despite the valid problems that you have mentioned.
If the capital class turns full fascism to destroy cooperatives then you have your revolution. But for capitalism, cooperatives are just another member of the capital owning class. Everybody wants a monopoly but not everybody gets it.
The key problem is the reserve army of labor. If cooperatives show some restraint and don't destroy labor market rates by cornering markets themselves and distributing that surplus, then capitalism can continue uninterrupted. Not everybody wants to participate in discussions as much as cooperatives require.
If everybody wants to be a socialist then cooperatives should even create incentives to maintain capitalism. That's where I lack knowledge. I don't see how value can be determined without competition. Do we want a society without value?
Let the capitalists have their boats. You need people who dedicate their lives to business processes. There is enough value created when there is a choice to work in a socialist cooperative. Communism is not only prevented by capitalists but also by the people themselves who don't vote differently. Capitalists work with those weaknesses while communists hope that they are not a problem.
Cooperatives don't have to pay owners nor a management layer. Workers also shouldn't slack. These advantages should overcome the benefits of exploitation.
Ussr won space race and lost the microchip race. The availability of cad systems created a big advantage.
Capitalism is not inherently self destructive. Exponential growth is only needed if all investors should succeed. That's not necessary.
Capitalism will thrive when times get tough because the majority will choose to compete instead of cooperate. Cooperatives could create space for those who want to cooperate.
