However, the contrast between laws that aim to advance a public policy aim and laws that aim to prohibit or restrict wrongful conduct may be ill drawn. Suppose that disparate impact laws amount to a mild form of affirmative action. The law requires that if an employer can choose among several alternative employment practices, all roughly equally effective in advancing her business aims, she must choose the one that does the most to advance the hiring and promotion of members of protected and under-represented groups. If the affirmative action goals the law promotes are worthwhile, and disparate impact is a reasonably effective means of advancing them, then the individual arguably does wrong by not cooperating in this social justice initiative by conforming to law. The wrong does not consist in conduct that can be characterized as immoral apart from the existence of the law, but is simply wrongful violation of a justified law. (An alternative view would be that if there was a widespread voluntary practice of accepting certain restrictions on conduct to advance a social justice goal, an individual who deviates from the practice without good reason would be unfairly failing to contribute her bit to this justice-promoting practice and hence behaving wrongly.) This train of thought assumes that the scheme to advance the social justice goal does not unfairly disadvantage an affected class of people, but this constraint does not necessarily demand equal sharing of burdens among all members of society.  Sometimes the fact that one is uniquely well placed to advance a worthy goal at small expense to oneself warrants requiring one to absorb the costs of taking the necessary steps.
