Uh, no, and yes. This post is typical of the lack of clear thinking surrounding this issue.
Corporations are legal constructs as a vehicle for ownership of property. So, the corporation is a "creature" of the US (I suppose) but the US, as a government entity, has no moral claim of ownership on a corporation. Unless it bought it.
Corporations are the creations of the state's power to confer some kinds of limited liability to a business. A corporation is formed to insulate its individual administrators from personal fiscal responsibility for the corporation's activities, and for other purposes, mainly tax purposes.
A corporation is solely in the business to provide products and services and make a profit while doing it. They are completely and utterly the creation of a state, without which they would not exist.
