The foundation put forth in the Citizens United (The name is repulsive) Supreme Court case is deeply flawed and an insult to reasonable thought. Corporations are not people. They are not required to defend our nation against threats with their lives, they are insulated against prosecution for fraud, they are protected from taxes that you and I pay, they answer to shareholders at the expense of our people and environment, they are subsidized by tax payers without the welfare stigma, they can pollute our planet without penalties and they are not held accountable for promises not kept.
If it were true, that Corporations are people, people would be born with the same rights, protections and exemptions Corporations enjoy today. People, of course, enjoy no such equivalent treatment.
