You'll notice that the rise in media reporting on systematic racism correlates strongly with the rise in discussions about class difference, industry trends, globalization, etc. The latter was Bernie Sander's platform before he was "challenged" by BLM during the 2016 primary. Not to imply that Sanders didn't previously support BLM, but he rhetoric changed after that. It was clear to me that Sanders thought the primary issue was class and that by addressing that we would improve everyone's life who was affected by the economic troubles due to the issues you mention. It's almost as if someone has something to gain by splitting us apart rather than letting everyone focus on their common issues.
Perhaps that's not the case organically but it seems that way because the media has been beating that drum relentlessly for the past half decade or so, in the process creating the actual strife they had been magnifying.
Class solidarity is non-existent in the US. Racial issues are much more visible. Poverty tends to be chronic and society to this day attempts to dismiss it as laziness or personal failure on the part of the individual, there isn't really anywhere for a flashpoint to happen. Incidents like George Floyd's murder act as a nexus around which debate, protests, and change can form.
The history of the US is far more rasist then it is classist; and there has been far more social movements along racial lines then class lines.
While we have had (successful) class based movements in the past, there is no class based analog in US history to the civil rights movement, or abolition. Even school children understand what Martin Luther King day is about; most American's couldn't tell you what Labor Day is about.
When there was a global movement for class based solidarity, the US found itself on the other side of the fight. (I'm referring to cold war era communism).
Even if a class based approach makes more sense now; there is a lot of institutional and cultural inertia behind a race based approach.
