I believe corporations are like unions, churches, and synagogues in that they are shields behind which people can hide from litigation. Corporations are "entities"; they are not referred to as he or she but as it. We do not refer to people as "it". Business men and women need shields to protect them from their victims - be they other companies, corporations, partnerships or the general public. The United States, its 50 states, president, members of congress and supreme court justices are protected by "sovereign immunity" which basically means they cannot be sued in their official capacity. People who form corporations do so for the same reason, protection. Imagine, if "we the people" could sue corrupt politicians for their misdeeds! Imagine, if greedy corporations bent on poisoning or endangering the lives of citizens could have their owners sued or brought up on criminal charges. If you or I tried to poison someone, we would be on trial for murder; if a corporation tries to poison hundreds of thousands by contaminating water, through fracking, for example; they get a slap on the wrist. Why be a person when you can be an entity? Is there anything better than sovereign immunity?
