Yes, I definitely agree that the Court's record is one of service, but it has often been service to narrow, vested interest groups rather than the Constitution. When it is difficult to see the separation between the members of the court and the people or groups about whom they are giving favorable rulings, it is perfectly reasonable to say that the court is corrupt, and to suggest otherwise is extremely blinkered.

While precedent has been built on the notion that the 14th amendment applies to corporations, there has never been a Supreme Court ruling on it. So the question persists and has not been settled. Maybe it will be this time, and maybe not.
