I have many problems with the Borg. But some elders being rich is definitly not one of them. Good for them.
I have a BIG problem with it for one simple reason: It provers JWs do not believe what they preach.
When an elder gives a talk telling the entire congregation that Armageddon is "close," coming anyday now, and we (meaning everyone except me, the rich elder) must "simplify" their lives for kingdom interests and not be wasting time planning for retirement, living the good life, developing a career, etc., while the elder is doing the exact opposite, it is ultimate hypocrisy.
If these elders really believed the end was close/soon/coming anyday now, they would sell everything they have in order to preach WT's life-saving message.
If they don't believe what they say from the platform...SHUT THE HELL UP !!
I have no problem with any JW being rich. But don't condemn riches and the good life for everyone else while simultaneously building your own empire.
