In a snit: Are we getting stuck with the dirty work?

I'm having a tiff with Ford Harding, the rainmaker guru to professional service firms. 

He wrote a blog post, claiming that, especially in small professional service firms, marketers and business developers cannot succeed at fulfilling all the conflicting roles that are required of them, so they inevitably sink to performing the least strategic function -- doing the marketing and selling dirty-work, instead of growing into more strategic roles.   

Ford, go pop an antacid, for gawd's sake!  Take a look at my reply.
