Corporations are not people. Corporate personhood is a legal fiction. It is useful to give corporations the rights of people, and is one of the great business innovations, but it can go too far.
Allow corporations to have a separate identity, and to sign contracts as a person, seems to work very well. Limiting bankruptcy to the corporation many times, but not always, works well. Saying corporations can not be owned, because that would be slavery is insane, and does not work well.
Corporations are not people, and can not make decisions independent from people. There must be someone who pulls the strings so to speak. The final say should be with the owners, who are the stockholders. There should be limited limitations placed on that relationship by the state, who allowed this legal fiction to be created.
What should not happen is some CEO, or manager gets unfettered control of the corporation.
