If you enact fully automated luxury space communism tomorrow, sure. But in the meantime, we must be pragmatic in how we direct our resources. Moderates have long reminded us of this. This means that certain groups can merit specific attention.
Again, look at the Maori. You cannot in good faith pretend that it's all just an unfortunate coincidence that a population of dispossessed indigenous people score lower across the board on economic and health metrics. The only way to reconcile this reality with a refusal to acknowledge the role of racism and colonialism in creating these conditions is to suppose that there is just something about the Maori, about their culture or their genetic makeup, that more strongly predisposes them to poverty than whites. And even if you don't say this explicitly, other people will, and if you refuse to contest them in substantive terms, if you refuse to offer alternative explanations for these conditions, then their argument is the only game in town, and the problem of Maori poverty is never acknowledged as a problem, at least not beyond a vague wistful observation that, wow, it sucks that the Maori are poor, but it wouldn't be right to spend any extra money on them because it will make white people sad.
It doesn't even need to be something conventionally "idpol". In Scotland, there is a long history of rural poverty, especially in the Highlands and Isles. Recent governments have spent a lot of time and resources trying to address that. It isn't a big sexy issue, it doesn't have celebrity-lead twitter hashtags. It runs against traditional assumptions that rural poverty is a by-product of the culture of these regions. And it requires them to spend more money on people living in those areas than in the more populated Central Belt. But the money they spend in those areas goes further, it helps break cycles of poverty and create a foundation for future well-being that regionally-indiscriminate spending would not. Should these politics be abandoned because the construction worker we have imagined doesn't care about child mortality rates on Skye?
