I don't understand this line of thinking for a couple of reasons:
1) Framing diversity as being about white people avoiding anxiety by surrounding themselves with people from other ethnic groups is egocentric and weird. Pushing for diversity is ideally about expanding access to lucrative careers, not bringing in people-as-window-dressing.
2) On the note of lucrative careers, comparing membership in a well-paid, prestigious career field within (say) the United States with being born in a more ethnically homogeneous country is disingenuous. It's the very fact that we don't live in a mono-culture that should make us wonder about the high correlation between being white and male and being in our field.
