You are WRONG.  The first slaves were white.  And if you could catch a native American,  you could enslave them,  as  Indians also  practiced slavery.    The issue of black slavery was to displace poor whites in a  class oriented society in the New World.    Georgia,   formed under Oglethorpe,  was not a slave state because Oglethorpe believed slavery demeaned  poor whites and took  their means of a livelihood.  When his influence was lost to old age,  South Carolinians prevailed to make Georgia a slave state.  It was about economics:  you don't pay slaves.  And thus the South kept European class  as a societal and economic   force alive in America,    and poor whites in poverty by slave owner's  control of government.  
  This election was about  white trash America being galvanized to vote and determine the Presidency.   The collective angst over Trump is about loss of power by government, academics,  and the entertainment and media elite.
