The question becomes who determines the size of the stake. Without equal ownership in the business isn’t the relationship between me and the other workers more akin to an owner -> employee relationship as opposed to a co-ownership? If I’m the only one who can make execuitive decisions, determine the rates of profit sharing, choose who gets hired and who gets let go, it doesn’t seem that much different than how things might look in America today, for instance.
Suppose the contract I draft up is for $5 an hour and 1% of the excess profits, split evenly among all non-owners, I see no difference than hire things look like in Starbucks.
Another way you could achieve this is by hiring bakers of equal skill level and splitting all the tasks evenly among us!
