Law firms have historically been extremely hierarchical places.  I do think that hierarchy is flattening out, but Matt Homann has correctly seized on one of the unfortunate anachronisms that still persists in many firms - the binary classification of people in the organization into a) "lawyers" and b) "everyone else".   Other degrees and other skill-sets  can and do add value.  I think it is inevitable we are going to see a continuing increase in professionals from other disciplines working inside law firms as leaders seek to adopt advantageous strategies and thinking from the larger business world.
