In a set of two posts (here and here) Yudel Shain makes some interesting points about the Doheny kosher meat scandal in Los Angeles. Shain makes a good case for negligent lax kosher supervision driven by profit concerns. He suggests that the kosher supervision agency at fault, the Rabbinical Council of California (RCC) minimized the violation when it was detected and rushed through the sale to Rechnitz, the son-in-law of Rabbi Yisroel Belsky for financial motives. If Doheny was out of business for a while, the competing kosher purveyors under supervision of other agencies would have picked up too much of the business thereby depriving the RCC of their income from kosher supervision. I do not know the truth but I find the allegation very plausible.
While kosher agencies make it a fetish to pronounce themselves not-for-profits, Shain points out the income of the operations still funds agency salaries, and the more income the higher the salaries can go, especially for those in charge. I would add that the same is increasingly true of yeshivas in the haredi world. Legally they are not-for-profits. However they are always inherited by the founding families even if there is no formal legal basis for this practice. In contrast many more modern orthodox institutions are not-for-profits genuinely controlled by their boards. But most haredi yeshivas are businesses disguised at not-for-profits for tax purposes.
