There is another model, which is state-backed or mutual-backed investment banks that provide initial capital for private businesses in private-public partnerships. Germany has a system that does this to an extend with its landesbanks. It works. Combining this with a worker-owned business model, you avoid the creation of a parasitic rentier shareholder class.
The reason this doesn't happen isn't because shareholder capitalism is more dynamic or more efficient. It isn't. The reason it doesn't happen is because the parasitic rentier class clearly doesn't want it to happen - it would remove their source of unearned income, but it is this source of unearned income that puts them in the positions of power that allow them to maintain the system to their own advantage. Breaking that position is the problem faced by the rest of us.
