A racist society is not a healthy society, for the perpetrators of racial discriminatiion as well as for the targets of that discrimination.  In an earlier book, Joe Feagin and his colleagues argued that all Americans have paid a heavy price for continuing racism:

Racist notions have brought ill-gotten resources and benefits to many white Americans. Yet few whites realize the heavy price that they, their families, and their communities have paid and will pay for this institutionalized racism. White Americans have paid greatly in the form of their ignorance and fears, in human contributions and achievements sacrified, in the failure to create a just and egalitarian society, in the resistance and lashing out of the opressed, and in the fundamental ideals and egalitarian morality thus betrayed.  In our view, U.S. society certainly cannot afford white racism in the long run, for it may well destroy this society as we know it sometime in this century.
