American racism toward blacks is expressed by the lack of funding for schools in poor black neighborhoods, by police misconduct; by the attempts to restrict voting by blacks, by the gross uncaring about the loss of black lives at the hands of authorities; by the disproportionate incarceration of blacks; etc.
Suggesting that the competition for jobs ought to be between blacks and non-American whites strikes me as odd.  Why would the appropriate competition not be among Americans of all races?  Why shouldn't we invest more in the education of black children from disadvantaged communities, and provide additional training for unemployed adults, so that they would be qualified for better-paying jobs?
I don't believe that the solution to the problem of racism is to enable blacks to take the most difficult low-paying jobs in our society.  That is what existed in the pre-civil rights era.  It's hardly something that we ought to consider as a goal today.
