I believe the Democratic system is so easily exploited because of its cause, for the people, for you. Which makes the person easily believable who is selling it and you blindly follow him.
Democracy is the highest mis-utilized thing now. Its exploited by almost everybody even by people who do not carry any power. Its misused by good people only in negligence and innocence and mainly not to harm anyone. But people with power use it to their fame, name, money and convenience and also to harm people and get benefit out of it.
