The black professional class are these individuals worst enemies. The more laborer and poorer classes are more likely to see the effects a little later. Disempowering, disenfrancising, and decoupling blacks from wealth and working toward parity with other groups is first on the agenda. Because these people have more influence and power than the lower classes and therefore need to be defeated first. Once everyone is effectively in their "proper place" then more broader oppression can begin and will impact everyone more equally.
So, basically, the wealthier blacks or well off blacks probably should be the most concern in seeing immediate effects. There is no bigger insult to these people than seeing blacks in professions like doctors, engineers, teachers, in government position, in the cubical next to them at their "prestigious" job, and so on. A black who is shoe shiner is more aligned with where they believe blacks should be anyways so they will get less attention. Not to be hyperbolic, but the nazis did this as well. They went after the jews in prestigious positions first. They wanted them out of government, education, finance, various prestigious jobs, and cultural institutions first and foremost. This was some of the first anti-jew laws they passed when they came to power banning and removing them from those areas of society.
