Corporations are no longer required to stick to a specific area of business laid out in their charter. They can participate in a great deal of endeavors, and can even buy other companies that are completely unrelated to them, and it is very difficult to have a corporations charter revoked. Many of our countries founding fathers feared that corporations could gain enormous power if not strictly regulated, and their fears have become reality. People tend not to realize that corporations have no real right to exist. If those in charge of a corporation do not run it in such a way that the majority of the people benefit from it, its right to exist should be revoked.
Corporations are legal entities given the rights of people.
Unlike small businesses whose owner is responsible for its actions, leaders of corporations cannot be punished for its actions. Under the law an individual cannot be punished for the actions of a corporation. This allows corporations to commit crimes that individuals or small businesses would be severely punished for. They dump toxic waste, abuse workers, discriminate, bribe politicians, etc. It seems to me that if corporations functioned as they were originally meant to, most of the major corporations that now exist would have been eliminated long ago.
