Were you mormon? Or is this more widespread than I thought?

If you are talking about the mormon church, and if what I've heard is correct, you missed an added point that makes it look all the worse. That you had to pay for the right to let them do that to you. Normally in a labour trafficking situation you'd at least be expecting some sort of compensation, even if it's grossly inadequate and ends up largely back in the hands of the traffickers as they charge for accommodation and transport. But from what I've heard, mormons do the labour entirely for free, and pay a large amount for the "honour".
