Yes, inflation is up, but so are interest rates. If you owe money (credit cards, for example), it costing you more, but if you are investing money (remember WT is sitting on BILLION$) it's much more certain to get higher returns on your endowment.
I do not for one minute think WTS is broke. I think that is the appearance they want to spin for multiple reasons.
1) They cry "poor mouth" in an attempt to generate more revenue/donations from members. (God needs your money!)
2) They want the appearance of being short on funds to limit the damages they could suffer from further lawsuits. I suspect they have been busy "hiding" their money to keep it from the lawyers who are suing them.
