Episode 15. Was Aristotle right about slavery?

With the recent murmurs about cancel Aristotle the mindcrime liberty discusses what this great Greek thinker thought on the topic.  Aristotle argues that a natural slave exists and its actually in the slaves interest to be ruled by the master.  Is this the case? Do these classes of persons exist or is Aristotle analyzing the contents of an empty box? What would be the historical/universal definition of slavery if one would want to postulate it in general. Would taxation or wage slavery be included as thinkers like a Hans Hoppe or Marx would argue respectively?  What about serfdom or even voluntary slavery? Is voluntary slavery an oxymoron?  Does slavery of any kind,  including the voluntary kind if it does exist, actually benefit either party.  Depending on the definition were most humans ever really free from slavery of some kind?  If slavery is so bad who today is actually enslaved and why don't we discuss that or all the other historical slave trades? We finally discuss whether paternalistic policies work and whether they are advisable to either parties in the relationship.
