It is definitely hard to thread the needle of being aware of american history and also having enough optimism left over to be motivated to affect change, I will grant you that. Your pessimism is well warranted.
Respectfully, I will point out that your view is, in a way, kind of paradoxical. You are right to say that white people in this country cannot be trusted to improve the lives of non-whites however, this phenomenon is not unique to the white community - it is mostly just amplified by their disproportionate power in society. That in mind, consider what this implies in relief: the myriad constituencies of the oppressed minorities in this countries will be able to, in a coordinated way, set aside their own priorities to mutually advance the causes of other non-hegemonic groups in a way that is separable from the economic conversation while overcoming white hegemony WITHOUT white participation.
Looking at the way the latino community voted in 2024, and black men's feelings about gay and trans people, and the complete implosion of solidarity among women as a voting block...this doesnt seem like a winning strategy, nor is it clear that this coalition can ever surmount the white hegemony. The only group that ever seems to participate in politics in this way reliably are black women, and god bless them for it.
On the other hand, rewind the clock to 2016 and 2020 and you see that movements around economic issues like universal healthcare have a ton of steam given the support for Sanders and AOC, among others. I want to be clear, fuck the dems, but these are illustrative examples.
All I am saying is that the most annoying white people you know have been saying for years that they are deeply reactionary to racially specific policies while also communicating clearly that they are also fucking morons. TRICK THEM. Advance policies that are nominally race/gender/sex/etc. neutral but would disproportionately work to fix racial/gendered/sexual/etc. disparities...like universal healthcare, like rent controls, like public works projects (trains, housing, etc.). You are bound to get a few of them onboard and motivate fewer of them to oppose you. The combined effect might be enough. God knows the current strategy is doing the opposite of working.
