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.
It is time to kill the term Non-Lawyer. Law firms are professional services businesses and its time to acknowledge the large group of diversely talented people who make them run — people who don’t deserve to be labeled “non”-anything.
