@Frank Apisa,
Come to think of it. We all are slaves to many. Why? Because of how many mess with our heads. Getting us to do, or say things they want us to do or say. As I've mentioned. Slavery consists of controlling one's mind. Messing with one's head causing them to do as they want.
For example. If one, being that right one, your in a way owner is going to mess with your head with the intentions of making you do as they want you will do as they want.
