Part of the issue, according to Goldenberg, a retired Navy captain, is red tape. Medics and hospital corpsman in the Navy, despite having years of experience in the medical field, have to start from square one should they wish to pursue a career in medicine. Without having additional schooling, they're unable to come out of the military and become an EMT or paramedic. The same goes for truck drivers. While they're used to driving 18-wheelers in less-than-ideal conditions, they can't automatically qualify to drive tractor trailers on roads in the U.S. because they haven't been taught how to reverse the vehicle unassisted.
