Why isn't "Corporate Personhood" in the common discourse?

If it isn't already clear to you, I have news for you. We don't live in a Democracy. It's becoming clearer to me today why. "The existence of corporate civil rights is the driving force behind the erosion of individual and community rights, the destruction of our democracy and of our planet."* (I can say this no better.) What is at the heart of a moment we laud in American history at Boston harbor in 1773? What was Senator John Sherman of Ohio dealing with in 1880?

The criminal abuse that is Corporatocracy, my friends, that's what. What to do about it? Well, first the truth has to get out there. It has to be understood by many more people why something that happened in 1886 is central to this mess. The national consciousness has to make a sea-change, and now. People have to take it on themselves to resist the on-going interests of the investment classes dumbing us all down.
