the myth there is a teacher shortage is based on attempts to felicitate increases the value of their job position.
the FACT IS there is a huge shortage of all skills and few people want to work that hard, Yes students make it a unpleasant job but the teachers are often well paid considering the limited other ability they have.
if you want to have something repaired say plumbing, or electrical remolding; MOST teachers could not do those jobs without years of On the job training.
but the young do not want to learn and cannot show up at 8 AM on time, so they are not learning ,,, soon there will be no one to fix your leaking roof, or repair holes in the driveway or repair your evaporative cooler.
in short there is a big shortage of trainable people to work and it will make our lives harder
teachers are in no more shortage than others ,,, and with the affordable care act (Obama care) no one will want to be doctors either
and no a degree in liberal arts does not qualify you to be CEO of a mega corporation starting at three times the salary of teaching ..... I heard that my whole life from mom who was a 2nd grade teacher
