1. Not much in it, but probably not true currently.2. Yes, but there are exceptions. Think about it like this; most people that are successful at start-ups were not formally consultants. Do you therefore consider that if you were an experienced consultant that you would be at a real disadvantage? My guess is that the reverse is true, because having been a management consultant you would have insights into how to manage a business. Working in consulting or having a top MBA puts you in a real minority, but that is not the same thing as being at a real disadvantage. 3. They are an investment. The fact that some firms fund MBA's, often very financially astute firms, suggests to me that they are worthwhile financially.You are sensible not to think about going to B-school without sufficient experience to relate an MBA to. It can be done, but I have often heard sensible business people advise against it. My thoughts are that the consulting industry is better off with a good mix of people (MBA's and non-MBA's etc.)I can't help thinking that some of those suggesting that you must have an MBA, or must not, are being very subjective. They are often simply justifying what they have done. Nothing wrong with that except that it could very well be the wrong direction forward for those considering their careers longer term.
