I will be dan lekaf zechus, that this question is asked out of curiosity and innocence. If that were not the case, I find it incredibly ignorant.
There is not a career without its nisyonos. Yes, kollel yungerleit who invest themselves in their learning are challenged with many things. Many are pressured to provide their homes and fmailies with more, and their ability to be mistapek bemu’at is limited. They can easily follow temptation to get involved in various ruses to claim entitlements that they should not get. Such gezel can become chilul Hashem. One would think that being machmir on kashrus and shiurim would accompany uncompromising honesty in money matters. I am not accusing anyone. These infractions do occur, and I am drawing attention to the reality of the nisayon.
The entire business world, retail and wholesale is full of huge challenges. Genaivoh, gezailoh, genaivas daas, ono’as mamon, ribis, etc. are immense challenges.
Chinuch is not simple either. Embarrassing a talmid is a huge aveiroh. Even the talmid who requires a disciplinary word must not trash the dignity of the child. Malbin pnei chaveiroh is serious enough to block a person from his otherwise destined olan haboh. The Rambam specifies that this includes a victim who is a child.
Rabbonim can pasken wrongly, they can neglect a congregant, they can address a conflict situation while violating shemo’ah bein acheichem, etc.
Every aspect of our world is frought with nisyonos. Now let’s consider the positives:
There is a desperate need in Klal Yisroel to have professionals able and willing to address personal problems. Having such professionals who can perform these needed services without compromising on Torah value is critical.
The mitzvah of restoring, or helping to restore, the simchas hachaim for an individual or couple is huge. Gedolei Yisroel have addressed this subject in numerous ways. Some refer to a mitzvah of hashovas aveidoh. Others to being a shaliach of Hashem to bring about refuah. The Rambam addresses the matter of cholei nefesh and cholei ruach, and equiates it to cholei haguf.
Every barrel has its rotten apples, including the few fields mentioned above. I sincerely hope the question posed was out of ignorance or curiosity.
