HairTrigger, I'm not an expert on WT, but, they were selling off Brooklyn properties years before 2013. I'm sure there are threads here on the subject. P lanning to purchase property took years, too.
I'm sure WT has a diversified portfolio. I know the NYSE has grown in leaps and bounds for the last couple of years. If the WT didn't sell off when stocks were falling,.they have recouped their losses by now and then some. I also believe they are big money players with hedge funds.
They are fearmongers. They themselves are fearful and also create a certain amount of fear in others. Having a self contained compound is a wonderful thing for any cult. Keeps a tighter rein on believers. Keeps out outside influences. I agree with Lisa Rose.
Why are they cashing in their chips? Because they can.
