Yes, they are; but there's a "dual effect" that goes on...a high % discover some things about Mormonism -- and about themselves -- and slowly jumpstart their eventual exodus out...But there's also a % who are "steeled" by the experience...and, long-term-wise, wind up being both higher givers to the cult as well as a key pool for future leadership fodder.
