Have you heard of wage slavery, where people use the term to focus on similarities between slavery and wage like owning and renting a person
I have.  But I do not know a lot about it.  Can you explain?
People generally use it when referring to situations where a person's well being depends on wagers or salary, maybe like someone who lives pay check to pay check
So it is basically when the employees have all of the control and the little guys (employees) are at their mercy
Yes, it has been going on for a long time, there are a lot of the similarities between wage labor and slavery as early as Cicero in Ancient Rome! 
Cicero was one of the people against Julius Ceaser right?
Yep, he was a Roman Politician and Lawyer as well
I used to watch a show called Rome on HBO and he was featured on it
I bet it was a great show, I don't have cable so don't get to watch anything good haha. Did they ever release it on Blu-ray or DVD?
Yeah, both seasons were released on Blu Ray and DVD.  I would recommend it highly
