In the context of 1967, he's talking about taking to the streets and creating a separate black nation in a concept called "black separatism". Nothing about that is against the idea of a company making sure that they have a diverse set of employees across the structure of the company, if we can stay on topic. Nothing about it rails against "identity politics". He's not saying, if you read the whole book (which you should, it's fantastic), that the black struggle doesn't require a different set of tactics from the poor white struggle. Only that there exists some overlap that would be served by making sure that every person in America makes a good living (in addition to other separate struggles). Particularly since black separatism in a lot of cases meant leaving the US and the society that was built using quite a bit of under(or simply un)paid labor and the wealth that belongs to all here.
I'll give you that anyone saying that _only_ corporate identity politics can solve racial issues in America is blowing smoke up your ass, but honest looks at why companies as their employees become richer trend white and male is an important component of the fight for racial equality.
