"If you refuse to pay taxes, we might have a better life!"
Of course, there are also those who kill vagrants for fun, or push them off the train tracks, generally for similar reasons, thinking these vagrants waste their tax money and are better off dead.
Such events can happen even in modern rule of law societies, so it's not surprising in a place like Seth.
Of course, this also has to do with the system in Seth. Second-class citizens have no rights, but they also have no obligations. That leads to them not having to work, leading to the question... what's the point of their existence... only heaven knows.
Is it just to bear and raise more magicians?
Are second-class citizens pitiful? Yes, they are. They eat poorly, dress shabbily, live in subpar conditions, and are divided by class.
But...what's the point of their existence?
They can't fight as soldiers, can't work, they can't even do manual labor.
So what is the meaning of their existence?
