Everything that rises will fall. Empires, societies, governments. None of them lasts forever. Why? Because even though they are the products of change, they become resistant to change. The longer a society survives, the more it clings to its power, and the more it resists progress. The more it resists progress- resists change- the more its ciizens demand it. In response, the society tighten its grip, desperate to maintain control. It's afraid of losing its hold.
