Slavery in the since of source of economy not human welfare. This was about the overall universal driver of all conflicts...money. If we use Stephen's tool of "watermellon eating in your underwear" and trade that with "the use of an illegal allien work force" or "non union workforce" or "non dependent, self relient, independent, non-currency barder system economy" it would really change the attitude of meaning of the kinds of political force being pushed and pulled.
