Just watch _House of Lies_. Marty Kaan and Associates will kick the ass of your McKinsey folks.
This fantastic show really gets at what consultants are doing. It was based on a book by a real management consultant. They all have their MBAs from the good schools. You go to a company, figure out what the ceo wants you to decide and is paying you to 'investigate', and then support them with a complicated opinion with numbers and accounting details (that a lot of people aren't going to investigate too carefully or refute). Offer 80% of what they need at that time, and a continuing contract to figure out the rest.
