Thomas Jefferson had more direct opinions on corporations, having tried (and failed) to add an 11th amendment limiting their power. For example:

"I hope we shall take warning from the example [of England] and crush in it’s birth the aristocracy of our monied corporations which dare already to challenge our government to a trial of strength, and to bid defiance to the laws of their country."
