I would suggest they are built on 3 legs:
1- Print publications
2 - Real estate
3 - Donations/wills
I would say the Internet has destroyed (1) print as a viable business model - particularly when there is no advertiser funding. (See skinny mags and move online for details)
(2) Real estate is going strong but the branch consolidation and move upstate indicates the 20 year view is not optimistic
As the elderly lower midddle wealth group Western cadre die off (3) donations does not look sustainable either.
My guess is the WTS are stockpiling cash from real estate to fund an investment-based financial returns model, supplemented by RBC circuit ass-halls and KH refurb and flips.
Any signiifcant strategic shift in these 3 areas is worth noting.
Thoughts?
