On one hand they are under a lot of stress running a religious ponzi scheme, whether they are awake or not.
On the other hand they are completely relieved of the normal financial stresses of life. They have zero expenses, a comfortable lifestyle, go-men all around them, 24 hour security, top-notch health care, etc.
Suicide? Nah. Even in a company downturn their life is way better than most by many measures. They have no fear of layoff either, much different than many of the underlings serving them.
