mckinsey is like if nathan for you was real and he was also evil
Once again I do not understand McKinsey's reputation. I don't mean this as a question of how much they're grifters; I mean that I can speak to management of a major company and say "you should take all the money for yourselves and leave everyone else to struggle" for a way lower fee than they must ask, if only because I'm just one guy and not a massive consulting firm myself.
In fact that's my first piece of advice, offered freely to any company seeking to cut costs and re-engineer. Fuck the McKinsey guys; hire me instead
