They are obviously skimming off the top for their well-connected suppliers- builders, accountants, lawyers, realtors, etc. They are obviously building nicer headquarters than they need. I mean, they could have sold all the Brooklyn properties and moved to existing New York state properties. If they are going to become a web religion, they could run it from one building.
I don't believe there is a false money problem, though. I think it's deeper than they let on. We do not get to hear about the pedo-lawsuits where a gag order was in place. We know that voluntary donations from non-Witnesses for the literature has always been tough to even ask for, let alone collect. We know that the expectation upon the members paying for the literature has been met poorly all along. We know that assemblies/conventions have been their cash-cows but we don't know if they have not kept up with the organization's money woes in other areas.
The thing with members is that they always feel that they give their time, so they only give so much money. I mean- straight up, if the Mormons encourage education and a male member earns $70,000 (USA) a year for his family, he gives his total yearly tithe of $7,000 and probably gives time also. Can you imagine a Witness anywhere giving that amount of money? If they drop $100 a month in the congregation box, $100 in the box at the Assembly Hall (both waaay high from what I have seen in years past) then they contribute only $1,500 a year.
