I'm not sure why we should expect all industries and professions to be racially and gender diverse in perfect perportion to society at large.
Different people and groups have different interests, and different jobs require a level of education that alters the racial and gender makeup of the applicant pool.
And, I don't think
@exmediahack or
@Alma are wrong or insensitive to point out that if you have one job, from which your applicant pool is 200 white men, with an average age of 33 and 10 years of reporting and on camera experience, that they might be better at their job than the person hired from an applicant pool of 30 (beautiful) women, with an average age of 25, and less than 3 years of experience.
