In regards to the MBA question - the reason as many MBA's are not affected is because of the life experience MBA candidates have before applying. A decade of life experience, in the form of an undergrad degree and some time working, means that MBA candidates have a much more realistic understanding of the benefits of further study. Add to that the fact that MBAs are generally slightly shorter, and as a group they are making wiser decisions.

In terms of the medical problems, I believe the free market will solve this problem if given a chance. The problem right now is that because such a large percentage of people do not pay for medical care out of their own pocket, they don't care about value for money. How do I know my Medical Insurance Company is not getting ripped off? Well, I don't. And infact, I'm insentivised not to care - it doesn't directly effect me.
