If you're for the business, no need for an MBA IMHO. But if you want to excel with the rankings in the academe or corporate, it's a ladder.
you don’t have to get a mba to read and learn if you have the will and desire then you can learn pretty much anything
The learning comes from experience with what we do and that's the same with business. Some get lucky that they find their success through their first tries.
But if we're going to speak the entirety of the whole circle of business, failure is the first step into success and look at the every successful businessman, they'll say the same thing. Having an MBA is like a bonus.
It's interesting that you don't think an MBA is necessary for business success, and I respect that point of view. But let us dig deeper: isn't schooling more than just a piece of paper? Yes, working in business is a great way to learn, but getting an MBA gives you a more organized way to learn about complicated ideas like finance, strategy, marketing, and so on. Mix of theory and real-life case studies, usually led by experts in the field. There must be some value in that. Believe it or not, schooling changes the way we think. You have to learn more than just how to run a business. You have to learn how to think differently about running a business. Doesn't the network you make while getting an MBA open up a lot of doors for you in the future? Also, wouldn't an MBA give you a more complete understanding of the business world, making it easier to travel through uncharted territory with confidence? Education does, in fact, enhance experience, which is priceless. Are we not valuing the larger view that MBAs offer when we brush them off?
