How was slavery different in the roman republic than it was in the united states?

In the Roman Empire, slaves could obtain freedom much more quickly than slaves during 1600s-1800s in North America. Also, in the Roman Empire, slaves were at times educated, held status within their households and were valued by their owners. That is not to say that all slaves within the Roman Empire had access to these aspects, but they were present and common practice within Roman society. In comparison, slaves in North America were not afforded these features, they were a source of labor and, eventually in the Southern Colonies, they became essential for the economy. Furthermore, slaves during the Roman Empire were typically ‘white’ and viewed as a person/human being. While in the North American Colonies, slaves were typically black or Indian, no white person was enslaved, and slaves were typically not viewed as having the same rights as free individuals, nor were they believed to be fully human.
