Only you know what credentials would make the candidate most desirable, but I would not generalize that most people with a degree will be less likely to pitch in and help with any kind of project, mundane or not. My husband has an Ivy League degree and work in politics. His responsibilities run the gamut from writing press releases, writing testamony for a hearing on a bill to stuffing envelopes for a fund-raiser. It's my opinion that having a holier than thou attitude will get you nowhere, degree or not.
yes i am responsable for it all though and I do have a degree.
and yes some of that is because she has a Masters but most of it is because she works hard and is good at what she does
