It's a good book, I'd recommend it, and you can draw your own conclusions from reading it. It's like 80 pages, too.

This is a weird subjective/objective thing. While people may not be chattel slaves to a slaveowner, there is a case to be made of bonded/indentured labor for many. The view of chattel slavery seems to fit well into dominant narratives, as it relies on there being a subject who is enslaving another. Modern conceptions of indentured labor, however, are under an objective threat of violence, and this doesn't fit well into dominant narratives of how exploitation works.
> If everyone is a slave then no one is a slave.
There's nothing indicating that the parent comment believes that everyone is a slave. In fact, there's nothing indicating in the parent comment that he believes we are enslaved.
Note - this is only just an observation.

Though it's not your intention, this blurring of categories justifies real slavery. If everyone is a slave then no one is a slave. If "bourgeois freedom" is an illusion then every kind of repression can be justified by the claim that it will bring about "real freedom".
Actually, the freedoms that we have are real and they matter.
