I think the article makes a pretty persuasive case why competence isn't a core selling point of McKinsey (or many other management consultancies) anyway. What many companies want is for an external party to tell them to do what they've already decided to do anyway, but would rather not take personal accountability for. They're paying for the amorality - if the suggestion comes from someone else, it's not _you_ being amoral, it's a consultancy with a prestigious brand that everyone else listens to, even if this unspecified "everyone else" is hiring McKinsey for the same reason you are: to defer blame for doing something abhorrent.
