In this universe are often high-capital-expenditure endeavours. You WANT the wealthy to take the risk on those, and not the workers.
For example, a co-op of 20 needs a million dollars to create a factory to build widget X. Where does this co-op get the money from?
What happens when widget X fails? Are the losses evenly distributed among the co-op members?
What co-op-ing everything winds up doing, in effect, is either 1) socializing the losses of adventures of politically-connected "wantrepreneurs" who are adept at converting political capital, or 2) making participating in risky ventures only accessible to the economically wealthy.
So in the long run enforcing it is likely to cause more economic disparity, not less.
The majority of businesses actually are proven and stable business models. The local convenience store is pretty much the perfect cooperative opportunity. There’s really no reason for 7-Eleven out of Japan to be owning most convenience stores.
Venture capitalism still has a place in the ideal mixed mode economy.[0] For those risky ventures. But that’s really not what the majority of the economy should consist of. And it doesn’t. We’re just really misaligned in our model for what the majority of our economy is.
Unions did a good job of distributing wealth in a free market way. But those still drive out capitalist businesses to cheaper countries. Cooperatives have every incentive to stay here.
The authority to define what working there is decided upon by the shareholders, it's a democratic workplace. So you couldn't be that person on matter how hard you tried. That's kind of the point. To finally remove the master-slave class tension from the our places of work and replace it with democracy.
