No, I don't think that those that are old are ever going to learn. When they are gone though, I don't think as many of the young people are going to follow in their footsteps.
I'm glad I'm not in the congregations now with all those needy older ones who never planned for retirement and old age. Many never even wanted to be in the workforce. The religion held out promises, special titles, being invited to special gatherings (the ones I wasn't "spiritual enough" or "theocratic enough" to be invited to). Yeah, well, let their "spiritual" friends give them money...Good luck.
