Great that Stephen could harness the resources of friends, family, and students at USC in order to provide cheap, quality labor in his early quarters of operation. One relevant consequence of this for Jessica, however, is that...

b) the students will graduate and move on to full time jobs elsewhere.
c) his early cost of revenue probably was not a realistic reflection of the full cost of refurbishing his electric motors.
