I fail to see how skin color, gender and "safeness," whatever the hell that is, implies someone has a "reduced" ability to detect and solve important problems. If you actually look for it, you will find many examples of people with the superficial characteristics you describe, and find that not only are they an extremely "diverse" group of people -- in the characteristics that truly matter -- but that they are doing precisely the kind of work that I think you speak of.
Why stop at people in "our field"? What about all of the people who possess the superficial characteristics you mention, but who also share an extraordinary amount of "diversity" and have had extraordinary success in treating important problems -- outside of "our field"? Doctors, scientists, engineers ... all over the world ... truly seek to make the world a better place.
Frankly I'm sick of the notion that "white, male and safe" implies a lack of diversity and a lack of ability or desire to detect ... whatever problems you have.
