The Myth and Propaganda of Black Buying Power by Jared Ball

It's thesis is that "buying power" as a proxy for political power is incoherent because the methodology is bad, the conclusions don't follow, and the institutions that propagate the myth have conflicts of interests.
I'm interested in how capitalism has captured revolutionary and ethical action with "consumer choice". That how we choose to shop is civic action to replace community and political organization.
