Some of this is the danger of trying to make quick changes. When a company states of a goal of diversifying in say three-years rather than gradually, you're necessarily going to lock out others from the less favored pile. But there are some things in his statistics that still reek of privilege. For instance:
Non-Hispanic white men (whom I presume his article intends to address) only make up ~28% of the population. I get that his point is that those in culture industries didn't move elsewhere, but he also seems to be implying this unfair effect his plaguing other industries too. I'm not convinced of that. I'll also note that he appears to be ignoring a pretty significant data issue: unknown race/ethnicity is common and prevalent choice in the data. And frankly many people that may be described as "white males" when looking at them may be claiming other ethnicities from their family background. I look white (mostly). But my grandmother was from China, and I often rotate between putting Asian, White, and prefer not to say on surveys.
