MBA's always had a hard time finding work.
There are a lot of them, the competition is great, and most companies will start them at the bottom of the letter.
I speak from experience. I have a brother that finished his MBA with straight A's.
It was still tough in the beginning.
This oudns like the self employment option might be more lucrative. Companies are usually more than happy to have a freelancer that doesn't require health insurance, worker's compensation, and having to grapple with with holding taxes.
