if you give 1 person all power...he will become a king, and a tyrant
if you give a few people all the power they will become and oligarchy, and rule the people like they are serfs
if you give the people all power , the 51% will control the 49% and rule over them taking away their rights......history has shown this to be true.
So you divide power into 2 half's, and no one has all the power to become a tyrant...because they don't have all power
everything i said is true about progressive in their early movement.
