So there's a reason to believe that you cannot have corporations serve the public interest without either breaking them up to limit their power or fundamentally redefining what it means to be a corporation, but you can have government serve the public interest while remaining big and powerful. If the federal government followed the views of the American public to the detriment of career politicians, we'd say, "Great, you're actually doing your job." If Amazon followed the views of the American public to the detriment of career managers, we'd be very confused.

(That said, breaking up the government sounds like a fine plan too, I just don't think it needs to be first)
