That does not mean that corporations should have no rights. It is in society's interest that they are allowed to speak about their products and policies and that they are able to go to court when another company steals their patents. It makes sense that they can be sued, as a person would be, when they pollute or violate labor laws.
The law also gives corporations special legal status: limited liability, special rules for the accumulation of assets and the ability to live forever. These rules put corporations in a privileged position in producing profits and aggregating wealth. Their influence would be overwhelming with the full array of rights that people have.
One of the main areas where corporations' rights have long been limited is politics. Polls suggest that Americans are worried about the influence that corporations already have with elected officials. The drive to give corporations more rights is coming from the court's conservative bloc — a curious position given their often-proclaimed devotion to the text of the Constitution.
The founders of this nation knew just what they were doing when they drew a line between legally created economic entities and living, breathing human beings. The court should stick to that line.
