From a friend of mine:
The libertarian outlook has major value in that it recognizes the liberties and freedoms of people, and says that government should have no authority there. When those freedoms are extended to corporations, the libertarian ideal turns immediately into a nightmare, not unlike the one we're currently experiencing. Corporations are not people. They completely lack empathy, sympathy, compassion, courtesy, loyalty, and honor. They are, quite literally, immortal and infinite psychopaths. Given the strengths of a legal person, they will act along the same lines as the worst criminals society has ever known while smiling to your face.
Whoever wrote it is spot-on. I looked for the source, and found it on slashdot. The entirety of the message is well worth thinking about. Here's the link:
