content: Because most people have been trained from birth to be manipulated and to manipulate other people.  Parents manipulate us and if that does not work, they beat us to teach that might makes right. Then we go to schools where they teach us those same things again. Reinforcing through emotional manipulation that the state is our momma and our daddy , it cares for us, it pays for us. Keep that message up long enough and it becomes, the state OWES us (carrot), If we don't do as the state says then we go to jail (stick)  Religions do the same thing , only their even better at it. Carrot and stick. Be good and go to heaven, be bad and go to hell.  Its because morality can be manipulated through emotion not just logic. You do not need silly facts to manipulate emotion.  "Give a man a why and he can bear almost any how."
