States will never be happy until rulers become philosophers or philosophers become rulers.
rulersquotes
You must contrive for your future rulers another and a better life than that of a ruler, and then you may have a well-ordered State; for only in the State which offers this, will they rule who are truly rich, not in silver and gold, but in virtue and wisdom, which are the true blessings of life.
The rulers make laws for their own interests.
