Smiles - the LDS is more a multinational company, than what it is a religion. There could be fewer than 1.5 million, temple recommend holders. To hold a temple recommend would be the equivalent of a baptised, full believing, Pioneer in JWland.
The LDS is the wealthiest religion on the planet. Close to a trillion dollars.
The 2 religions, have 2 different problems. JWs will probably run out of money before they run out of members. Where as the LDS will probably run out of members before it runs out of money. The LDS is not dependent on membership donations. Even if the religion side of the LDS collapsed. It could carry on as a corporation for many years.
