However food cooperatives are a special case in that the owners / members are also the customers, so I'm not sure how well this concept can be applied to other businesses.
The decision about what to produce, when to produce, etc., is a collective decision instead of the top management decision. This means skilled workers have the same vote as the janitors.
This sounds good in theory, but in practice the question will be where to draw the line on what to vote on. How much to produce? How to market the product? How the ads should look like? Running a business involves a lot of decision making and usually you delegate the concrete implementation of strategies to stratified levels of specialized management units for a reason.
The workers are also the owners of the company; therefore, they get to choose what to do with the profits.
I guess to some extend you see this with start-ups where founders and sometimes key members of the team get shares or options. The challenge that fully democratized corporations would face in this regard is incentivizing founders to actually start one. Why bother starting a corporation where you only own a fraction of the profits if you could start one where you can take as much as you want?
Worry about machines replace your job because it will lower costs? It's not a problem with this democratic corporation since the goal is to keep the workers happy.
Profit doesn't need to be the primary focus but refraining from the usage of machines that could make a job easier doesn't sound practical. I don't think there's a farmer in the world that has complained about new equipment cutting his work time in half.
