This difference is important because, while Democrats express plenty of concern for racial issues, “there's just very little reason for politicians to care about an issue that both parties largely agree on”. In this case, the issue being sidestepped is economic inequality, and by misidentifying this, you’re hurting the brown people who you’re trying to help.
To be clear, the result of misidentifying the problem is the persistent evidence of racial disparities, despite so much apparent effort to address it, because brown people in America have always been at an economic disadvantage (see slavery, Jim Crow). They weren’t just made this way because of an uptick in racial discrimination. Rather, they are staying this way because of a drop in economic mobility at the hands of “both parties”. Of course there is simply far more evidence to the latter than the former, so we should take note.
Of course, the wider issue is social mobility, which is contingent on economic mobility. Scapegoating the economic part is a dirty game and ultimately a losing proposition.
