Corporations are the only business entities that, theoretically, have perpetual existence.

 Corporations are the only business entities that, theoretically, have perpetual existence. Further, the corporation is defined as an artificial person (with all attendant political and business rights of a person) in the corporate law of the United States (this is not the case in most other western European countries). This perpetual existence coupled with the status of an artificial person and recent U.S. Supreme Court decisions affecting political contribution powers of the corporation have brought about concerns for many that a good boundary has been breached and that the law should reconsider the notion of perpetual existence of corporations (rather than have a corporate charter that expires every 50 years or so). How do you view the current status of the nature and powers of the American corporation? Is it the best model thus far or should some features be modified?
