There has been a lot so called self identifying religious organizations based in the US that were really businesses hiding behind a nonprofit tax exempt religion.
What makes the WTS/JWS stand out is that all the money it accumulates does not go out to help in local communities as in charities to help the disadvantaged.
This religious Publishing house is one that really was a business that exploited people's belief in the bible, the leaders interpretations of the bible and to push a tainted commercialized version of the Gospel of Jesus.
Exploiting tax exempt status by the WTS's leaders goes as far back as the early 1900's with the likes of J Rutherford. He intentionally deeded the property of a luxury home which he lived in San Diego as a relgoius compound to exempt from paying any local property taxes. He used the money of the WTS to live a luxury lifestyle, helped no doubt by the tax exempt "Religious" organization he ran the WTS./JWS.
