Well...I'm not referring to the taxes in the 3/5 Compromise. In fact, I never mentioned this. Sorry ...I should have been more clearer. I am specifically referring to the slave codes which were laws that estabished the status of slaves, denying them basic rights and classying them as the property i.e. chattel [not human] belonging to slaveowners. And socially, the term 3/5 human in regards to slavery became a staple in the language for slavery in America...also the one-drop rule was too a part of the racist dynamic. While the former gave slaveowners live and death control over their chattel, the latter was one of the teology proof of subhumanness and inferiority of Africans. However, my main and only point is that "laws" were implemented [depended upon which state] to prevent Africans from obtaining human status which for white slave owners were their legal jusitification for slavery.
