Unfortunately, there's a sucker born every minute. Somebody, somewhere, needs magical leaders to show them the meaning of life, and they'll pay for it.
The WTBTS can go 100% paperless, sell every single Kingdumb Haul on Earth, tell congregants to meet in someone's home, rent facilities for special occasions, still get donations to cover expenses and STILL get free labor on lucrative properties!
Why? As long as they are perceived as "The Channel", J-dumbs will follow them! There will always be plenty of religitarded people who want to be "somebody" in the ORG. To retain that power, they must maintain the illusion.
Unless the Pedo issue becomes so bad that being a higher-up = jail, what's to stop the ORG? They can downsize, continue to re-brand and white-wash, and get online donations from Mexico and Africa for decades.
