In his controversial book, "The Declining Significance of Race" (1978), scholar William Julius Wilson featured two major underlying themes: the effect of fundamental economic and political shifts on the changing relative importance of race and class as a determinant of a black person's life trajectory, and the swing in the concentration of racial conflict from the economic sector to the sociopolitical order.
