And yet, the fact is that among those 75% of blacks who aren't poor, a much higher ratio of them as compared with whites (even poorer whites) will fall victim to a great many life-impacting negatives, from poorer quality of treatment by medical professionals to discrimination in finance. The difference is definitely related to racism.
Also, his anecdote certainly isn't typical for poor folks or black folks, and especially not poor black folks. Overall he has a decent point regarding the "poor, racism beaten" stereotype, but it's not very well argued, in my view.
