The thing is: MBA doesn't necessarily represent the skills someone learns in the way of finance and business administration, it's a way of thinking that is acquired in the process of attaining the degree, if that makes any sense at all. Let's try it this way: have you ever played chess? If you have then you know that you need to be able to think several moves ahead, and plan out strategies for the endgame while you're in the middle of the game.
This is the type of thinking that companies want, they want people who are able to solve the most complex of problems and get things done in the most efficient matter possible. This sudden call for MBA's has those in education jobs scrambling, trying to keep up with the latest business lingo and policies. Those in counselor jobs are advising students in the right courses to take, and even those holding general teacher jobs are baffled by the way the market is changing.
Though the whole critical thinking thing isn't a course, says those holding teacher jobs, it is a huge part of every course, and it is actually woven into the fabric of the course material itself. Those who take the required MBA courses will be taught to think ahead and problem solve in ways that most people never will be able to. Those who cannot think in this way just won't cut it in either the business world, or the classroom.
Of course, having an MBA doesn't guarantee you'll be able to cut it in the business world anyway, and even those in teacher jobs know this to be true. Remember that there are many people out there who have MBA's, and they are all competing for the jobs. Do you have what it takes to compete with them? Can you solve the complex problems and get the job that you want? Those who went to the best schools are going to have the advantage, and this is where you need to shine. Those with teacher jobs are going to do their best to give you what you need. It's up to you to show a potential employer that you are the best.
That's what it all comes down to, are you the best, or aren't you? Yes, it's going to be hard, no one ever said that using that MBA to its fullest potential was going to be anywhere near easy. Utilize your skills as best you can, and try to impress those employers to get the job that you've always wanted. As long as you are vigilant, and know what you're doing, there's no reason that you won't persevere.
