Corporations should not have the same rights as people because corporations are meta-organisms and I don’t want to get out-competed by them.
The meta-organism is still an organism. The same laws of evolution apply to meta-organisms as to since-celled organisms. You are a meta-organism; you are composed of billions of cells, some of them h Sapiens cells, the majority of them not h Sapiens. Yes, numerically speaking, most of your cells are gut bacteria.
Your individual interests are not the same as your cells’. Your cells are just as well-off taking the CTV route and transforming into sexually-transmitted-cancers and infecting everyone they can as they are hanging out in your big toe, worried about getting sloughed off the next time you walk around barefoot. In a pinch, you’ll sacrifice your whole leg to save the rest of you–sucks for your leg, but good for you.
A beehive is a more obvious meta-organism. You probably already know all about bees, so I will attempt not to bore you by over-explaining. The queen bee lays the only eggs; worker bees, all female, spend their days flying miles back and forth to fetch nectar for the hive until their wings literally fall apart and they die.
The colony survives even if the majority of the workers die, say, in destroying an intruder.
The bee does what it has evolved to do, but I do not find such a fate personally attractive (despite my obvious affection for bees.) I do not want to be a bee; I want to be a person.
Corporations, like bee colonies, are meta-organisms. They are created, they live, they die. They attempt to get legislation passed in their favor. They will, if not controlled by some outside source, literally work their employees to death. Corporations do what is best for the corporation, or else what is best for the Queen Bee (management, CEOs.)
A world where corporations are given the same rights as people is a world where corporations change the political, social, and economic landscape to favor the continued existence of corporations, rather than the human beings who are supposed to benefit from them.
