Money replaced slavery and hereditary system, but became a new form of slavery and hereditary system. In slavery, one person owning another person's life sounds so unreasonable, but in a capitalist society, you have to dedicate more than half of your waking hours to your employer in order to earn enough currency to survive and live. Your employer, because you are not their property to take care of, can even exploit and manipulate you further, the only difference being that you can choose who your master is.
In ancient times, a person's status and profession were often hereditary, whether you were an emperor or a knight. We, accustomed to the new social system, find this absurd. However, money is such an important social asset today, it can buy your life, health, and even life itself, just as important as status and titles in ancient times. Yet people naturally assume it can be inherited by the next generation.
Our society may seem so advanced, having gone through so many revolutions and changes, but in fact, human social organization and cultural structure are just beginning to change. Will encryption and artificial intelligence change us as much as fire and agriculture did in the past?
