If you want to know where the future lies in my opinion it's education law and education consulting. With an estimated 6 million children considered DISABLED in some form - physically, emotionally, learning, whatever - thanks to very fast and loose definitions of the word DISABLED, you can become an education consultant or advocate to testify for the lawyers who are suing to force school districts to provide students - ANY STUDENT no matter how rotten or stupid - what's called a FAPE - a Free and Appropriate Public Education. I'll leave it to you to imagine how 'appropriate' will be abused by both parents and lawyers.
This is a huge industry and as more and more screw-ups in the classroom get transformed - with the stroke of a pen - from reform school candidates to 'disabled' and 'in need of treatment' that the schools MUST BY LAW provide, you will see America's education budget go into the stratosphere.
