Yes, I like those thoughts on counseling, and I agree.
For some Witnesses I've known, I think it would be an unkindness to try to force them out of their belief system. Perhaps they would start working more and thus be more comfortable materially, but they would also be missing the hope for the future that they always relied on. That's hard to cope with, especially for those expecting to see lost siblings or children in the resurrection.
And really, we know better than to equate the niceness of someone's stuff with happiness, right? You might see a sad, shabby house, but for them it's home. How can a casual observer say whether (a) they are happy or (b) they would be happier as an ex-Witness?
Anyway, since the Witness teachings don't hold up to objective scrutiny, the best way to be a committed Witness is to self-brainwash by studying as much as possible, stay busy in field service, etc. It helps to crowd out doubts.
