They have NOTHING else. They have been told to remain separate from the world. Translation: Stay away from all the EVIL worldly people. If they left the org they would have nothing and NO ONE. The older ones especially.
Our family never followed the party line on this. By us choosing not to adhere to this, we have been able to make a living. Those EVIL worldly people have kept our businesses/careers going all these years. There are some VERY good and generous people out there. They are NOT all evil!
