I think most everyone, including those of us who focus on race in our work, agree with King's policy proposals here.
That said, surely you know King supported both reparations AND universal programs right?
There's a YouTube viedo a few months before he was killed where he talks about the race-specific things that had been done for whites since the Homestead Act, and how now it was time for those who had been excluded, Black people, to come to DC and "get their check" too. He also admitted the legitimacy of reparations in a 1965 Playboy interview.
He didn't view it as either/or. He also openly supported race based affirmative action on multiple occasions becginning in 1961 and extending all the way through to 1968.
He also made clear on multiple occasions that the thing preventing class solidarity, which he knew as s Democratic socialist was necessary, was white racism.
So he (and you) are right about the importance of these programs you mention here. But he was NOT advocating merely universal race-blind policy. Not remotely.
