Well, the conventional wisdom says that recruitment at top law firms selects for candidates in the upper class. This article is saying we should adjust that; it selects for upper class men, and women are not benefited by hinting at higher status. Since that's what the article about, and since it's not about women being universally discriminated against in law, I think it's fair they don't point out that lower class women have it better than lower class men. Although that result is somewhat surprising, it's not what the article is about. The investigation behind that result would possibly warrant another article.
