Addressing the first question on the modern effects of the historical events in the video, my impression is that many of these vents are very recent generationally. Traumas and financial consequences and social consequences seem very much like they would be lived today.
I am blown away by the extent of the information in these videos that has been omitted from history classes. The more I learn about these issues, the more I feel history classes were designed to create the impression that racial injustice was a phenomenon that once occurred and was then addressed, which is clearly not the case.
