Comparing the inconvince of having to switch schools, not being able to volunteer and depending on healtcare/insurance to slavery is a massive insult to people that where and are actual slaves.
Actual slaves did not legally own themselves or their children. Their owners can did take children, parents, and spouse and sell them to different slaveholders so they would never see each other again. A slave could not say fuck this my master is rapping and beating me daily so I'm just going to leave.
If you want to a simple question to determine if someone is slave or not ask what happens if punch your boss in the face. An employe will be fired and never work their ever again, a slave will have to continue to work their for the rest of their life.
