A common sentiment about SpaceX and Musk is that the employees also believe in the mission of making space accessible and going to Mars. Musk has been consistent on that being SpaceX's eventual goal since founding it, and he stuck through it even when SpaceX was one failure away from missing payroll. All of his early employees still publicly support this mission, even after retiring or moving on to found their own space companies.
