WT does not invest. But people may have long-term investments made for example from before they became JWs and then the WT has inherited these stocks upon their death, and as far as I have understood it, US laws in certain respects are such that one cannot "get out" of the ownership. There are some very technical discussions here that seem alein to us non-US ones, but that at least is how I have been able to understand it.
Who the hell do you think you are, coming on here with your facts and reasonableness. We need more groundless assumptions and half baked theories dammit. And more posts starting with the word 'wow'.
