Just last month my daughter,sil and me had a conversation about the need for vocational training in public school. Today's society turn their nose up at the suggestion their kid might need a trade. In typical fashion they completly overlook the value of work ethic learned at an early age. When they were in school vocational was a 3 hour elective,1 hour classroom and 2 hours working for wages. The class wasn't broken down into specialties,classroom was checkbook management,creating resume,job seeking skills (boy there's one a bunch of people could use) managing time between education,hobbies and family. Other 2 hours could be ANY JOB where employer was willing to perticipate. SIL worked at an auto parts house,daughter at a custom bakery and a pharmacy who eventually hired their son while he was in high school. While working part time and attending college,one of the pharmacists approached him about going to work for a start up business. Today at 32 years old he is full partner in a growing multi-million dollar pharmaceutical company.
Getting back closer to what OP is talking about, this kind of education is healthy for the community and tax payers should push for them. This is far above my pay grade but many of you qualify as adjunct professors. Point being that a bookkeepers and a host of other occupations could occasionally teach classes which save's institution money making classes affordable when compared to full time staff with benefits.
