Does that criticism make sense given that the title of the article and opening paragraphs talk about the class disparity, and only get to the major gender disparity in the middle of the article?
I'm not the person you're replying to, so I can't say what they were thinking when they wrote their comment. I'm choosing though to read their comment as referring to the larger social context, rather than this specific article. I would note however that this article is classified under the category "Gender" in the Harvard Business Review.
