Positions should be given like jury - by random computer selection, you do one 3 yr stint, plus a year to learn the job, then you are withdrawn from the pool.

You are paid the salary commensurate with the responsibility the job entails.

In your 3rd yr you help train the next person coming along.

Your old job is held over until your return.

Those that want the job are not given it... polygraph shows the liars, and, their names are taken out of the pool. Polygraph administered by computer.

Could work.
