The work typically is pretty tough or pretty boring. You could be a soul collector, a torturer, a prison guard for souls. Or a crewman on the ferry of the damned to take souls lost in the seas to the afterlife world.
You do this job for 200 years after you die. The job will be without vacation. Without pay. Knowing all friends and family are happily living another life as souls in another world.
Would you still take the 2 billion?
