Since the SCOTUS gave corporations the power of person hood, our Congress needs to give them mortality, requiring a limit to how long a corporation can exist.
Why is this important?
Corporations were recently awarded person-hood, but one major difference between man and them is that they seldom die, giving them great institutional advantage over each generation that comes along. They outlast any foes and are able to monopolize on any weaknesses. They need to end just like humans do.
