BECAUSE OF THE PRINCIPLE OF “Rule of Law“ The U.S. Constitution sets limits upon what a people in a government can do, and what people in the citizenry can do, that cannot be modified. Under democracy, the ‘rule of law’ has been intentionally modified via propaganda to mean ‘rule by law we agree upon’ so that the government can enact any law that it desires. The american system was designed to make it HARD to pass laws, so that the government could do as little as possible. And presidents, especially since Franklin D. Roosevelt, have undermined that constitution whenever possible.
Americans historically operate under the anglo saxon principle of voluntary order: “I will allow the government certain actions for our common good, and disallow the government all other actions. If the government violates those actions I will replace it with a government that does not.”
