Vidiot: Since the WT financials aren't open for public review, there's no way for anyone to know exactly what goes on. But we are sure left to speculate.
In my bethel experience, I didn't see evidence of fraud, with someone pocketing money. However, I did see a lot of terrible decisions that cost hundreds of thousands of dollars. Since bethel would put people in responsible positions based on "spiritual qualifications" (or their ability to kiss the right as$es), inexperienced and uneducated people became responsible for important and expensive decisions. For temporary workers up to bethelites that only last a couple of years, they often don't see this. But when you stick around much longer like I did, you see the trend often repeated of expensive mistakes having to be corrected and covered up at "God's House."
