Yes, but they are different cultures in other respects as well. I would lay odds that these other cultures don't perceive the same gravity of consequence for loss of family honor, just for starters.
We didn't upset the apple cart as much as you may believe (and this is not to diminish the brave sacrifices and contributions of abolitionists during that era). The Industrial revolution had more to do with abolition than John Brown and Nat Turner. The changing economic landscape is what brought about the end of slavery. See that in England the institution and trade were outlawed before they were here in the US.
And even when slavery was ended in the US, the objective economic reality for blacks was largely unchanged for a century afterwards. Sharecropping, segregation, lynching, and Jim Crow enforced material conditions on blacks that were hardly distinguishable from slavery in rural America.
The recognition that slavery was abhorrent is a luxury for those who don't depend on it for the maintenance of their positions of cultural privilege. Yes, some people will sacrifice their material advantages for the sake of another, but it's not so easily done, especially if the alternative is a total surrender of ones security and protection.
