We literally had to enshrine the RIGHT to slavery into law during the creation of the constitution just to get southern state support, and that was before the cotton gin made slavery significantly more profitable. Then we gave those same states extra voting power based on how many human beings they could afford to own. Then the very institution of policing itself in America started as a way to catch runaway slaves, often in OTHER STATES that had OUTLAWED SLAVERY.

But sure, this system that obviously had a huge impact on how the country developed, how power structures were purposely designed, and how freedom even worked, TECHNICALLY wasn't the primary reason for rebelling, maybe.
