Jw / LDS have the opposite problems.
LDS are the most wealthiest religion on earth. Surpassing that of the Catholic Church, and comparable to that of Apple / Elon Mosk. However, despite their wealth they have a more inferior doctrinal and historical foundation to the church. Many aspects of the church has now been proven to be false e.g BoA, Kinderhook plates. The LDS would more likely run out of members before it runs out of money.
The JWs have the opposite problem. For a religion of it size,I'd say its assets would be quite modest. Well at least when compared to that of the LDS. However the JW theology has more credibility, as it was largely based on mainstream Christianity. With all the on going legal battles, I have to wonder how deep their pockets are. They would go bankrupt before it splintered into smaller groups.
