I am also concerned about providing such a legal tool for whatever reason, I suspect it can be used retroactively to justify bad/improper decisions/actions. For example, might I be able to hire another person of type x over other candidates that would produce a more accepted diversity and justify this choice with logic like, "our company deals with people of type x so ...." Perhaps not the best example, but it seems like legislating a policy that needs to be induced with some incentive (like profit or efficiency or access).
Still, it is my understanding that colleges do this all the time to ensure diversity across the student population, affirmative action exists ... I suppose the goal is substantially easier to agree upon that the means to get there (sounds like vacation planning).
