I think more workers than otherwise will come to understand this systemic exploitation clearly if leftists *quit* telling them *untruths* that (a) white workers benefit from racism & racism is in the interest of white workers and (b) the U.S. working class benefit from imperialism. It is Marxist intellectuals' job to explain clearly what exploitation is. Throwing untruths (a) & (b) out, of course, doesn't solve all the ideological problems, but it's a good start. The next step is to emphasize that (a') white workers actually *lose* in real wages and social programs by *gaining* more relative advantages over black & other discriminated-against workers & (b') the U.S. working class bear the abominable costs of U.S. imperialism.
Truth = the Good News. :-)
Intellectuals are useless unless they tell the truth to workers who need all-sided political education as Lenin emphasized. Truth is in the interest of the working class, even when the working class are not in a position to immediately make use of it.
