Cali was never a slave state, or a state at all in those days. Those days being over 150 years ago. If there is any “structural or systemic racism” there it is from the democrats of California. You can pay them all you want (from your own state’s money) but know going in it will not be enough. Why would it be? The gravy train ends then.
Of course the government at the time was just following the law, and failing to follow the law would have had national repercussions that I'm sure they didn't want to deal with.
Talk about mountains from molehills.
