The prodigal son was ok. Dad looked after him. Likewise if the penny drops with any of them that they are eating the proverbial pig food and decide to leave, for the right reasons they'll be ok. If they stay in it'll be a different matter. You really do have to leave WT for life to radically improve.
One thought - if someone chooses to spill the beans of what they know, there might be a living in it. But maybe even that will not be required. Its funny how well things work out sometimes when you do the best you know to do the right thing. You cannot always second guess what is going to happen.
