A "good" lie told a thousand times

 

"Enslaved Africans were the ones who built countries like Brazil and the USA"

A type of "anti-racist fallacy" ... which is based on positive racism (a kind of 'good' supremacy/example: "only the racial group x that built this or that country")

But even if every part of these countries had a significant contribution of slave labor, there is still no construction without a project and the vast majority were thought of or designed and supervised by white men...

Yes, slavery is an objectively immoral system, in the sense of irrational: unnecessary, excessive, cruel. But this does not mean that the contribution of slave labor in any society that has already adopted it is uniformly absolute, precisely because of the need for architects, engineers, artists, designers... the majority of non-enslaved people.

Of course, workers are always important, in the construction of houses, buildings, in paving streets... The intention of this text is not to deny the contribution of these groups, including those from problematic historical contexts, but not to deny the equally necessary contribution of specialized labor.
