Having read NewBoy's report of bethelites' lifes and how they are desperate for any opportunity to get a few $ and make ends meet, I venture that the WTS is well aware of it and, for its own interest, is encouraging them, without saying, to find a part time job in order :
- that they may not be considered by legal authorities as employed (exploited) workers by the WTS but actual volunteers who otherwise earn their keep,
- to let them have a smooth landing in real world, for those who will be laid off in the future. In this way, the society won't have to pay them unemployment allowances, in case some of them fancy to claim those before the courts.
