Students at Florida public schools will now learn that Black people benefitted from slavery because it taught them skills. This change is part of the African American history standards the State Board of Education approved at a Wednesday meeting.
The description of slavery as beneficial is not t.....
"Built on slavery" is referring to the benefits that the ruling class received by exploiting slaves and that exploitation is a core part of US culture. It reminds people that most of the population was not included in the "all men are created equal" documents of the time.
It is not a positive phrase about general benefits for everyone. It is a reminder that we did, and still do, terrible things and we should not forget.
