If you got rid of corporations, you'd basically destroy the economy, and prevent a new one from growing.
Well I (and I think most people) don't want to get rid of corporations, I just want to get rid of my government being run by corporations. Would it destroy our economy to have our representatives beholden solely to the citizens that elected them?
Me: "Hi, I'd like to complete your cancellation of our contract."
AT&T: "OUR cancellation? How do you figure that?"
Me: "Well our contract was for unlimited data access, and you have announced that you no longer offer unlimited data access, so that means you've canceled our contract."
Trying to be happy is like trying to build a machine for which the only specification is that it should run noiselessly.
