I don't read the parent comment as claiming that the people in power are not hard-working or talented, nor that they don't care. Rather, I read it as asserting that many white men have had the privilege of not having to deal with discrimination and harassment, and that it doesn't come to mind as easily as it does for underrepresented individuals. Just like a developer is going to spot defects in applications more than a non-technical user because they are exposed to defects more often and understand where things will fail, people who have lived discrimination will be more likely to see it where it happens, and understand where to look to find it.
