Please see this article in Asbury Park Press regarding welfare fraud by rabbis.
Also, years ago when Christy was a NJ state prosecutor there was another roundup of rabbis in a New Jersey corruption scheme.
As rabbis who are supposed to be religious leaders, they should know the difference between following Moshe and Hashem vs. worshiping the golden calf. See Exodus 32 1-5 and Exodus 20 22-23. The golden calf being a metaphor for materialism.
While there may be nothing wrong with pursuing materialism as a means to improve ones existence, there could be contradictions to the Torah if material gains is not the means but the ends. In other words, worshiping the creation symbolized by the golden calf, rather than the creator.
As an outsider I have always wondered why this paradox existed. Are there other religious texts in Judaism that conflict with said verses in Exodus of the Torah and emphasize striving for worldly gains as an ends, thus in effect worshiping the creation as a false god ?
