More than a quarter of licensed attorneys who graduated from law school in 2000 are no longer actively practicing for a myriad of reasons. A significant number from my year, 2008 hold jobs that don't require a law degree.
These articles should give you a glimpse into the situation. There were several others I really like from over the years, but I can't seem to find them at the moment.

I don't believe the general job market for nurses is as bad as it is for attorneys. People also have a great difficulty accepting a potential sunk cost, or refuse to believe that there's greater opportunity elsewhere once they have both feet committed somewhere.
