Because they actually run their own eleemosynary operations, they don’t pass the money through to other charities. That’s why this number is so low. It’s an incredibly misleading statistic.
Now, I cannot say they don’t waste money in their work. I cannot say that they don’t overpay staff. I cannot say there is not self-dealing or favors to contacts, but to say that they just pocket 93% of the donations is false.
