I am generally anti-MBA when it comes to consultants. As a consultant, you will have had exposure to most of the elements covered on an MBA. An MBA is really useful for someone who has been in industry, in the same role, for a long time -- and who, consequently, has "blind spots" in their business knowledge. But as a consultant, I think you will gain far less value from the qualification.In terms of raising your income, I think you are overambitious. I don't think you will magically walk into a strat job on 200K, nor do I think that an MBA is a prerequisite for entrepreneurship, if that is the route you want to go.
