No, but his symbolic value is outstanding. It is like ‘Chock-full-of-nuts Coffee’ making Jackie Robinson an executive VP when he retired from baseball. Did the slugger know anything about business or the brand that hired him. No, nothing. However, black people in New York liked to consume this brand and Robinson’s face on their advertisements was worth many times over his salary in saying CFN Coffee was the pro Negro brand of coffee. Same for this zero, it says to the highend business community that McKinsey is ‘loud, woke and proud’.
You’re prolly right. Purely a symbolic hire as you so aptly described.
