Plebiscites are the way to hand government over to the elite with the deepest pockets.
This was one of the chief reasons the founders set up the United States as a representative republic, not a direct democracy. Government is supposed to be run by elected representatives, not the people voting on matters directly. When legislators vote against the Constitution, or in ways that displease the people, they can be voted out of office. That is accountability. Those are heavier questions than most of us want to deal with.
