The ones you speak of who sold everything they had back before '75 and went north in a caravan and who were held up as a good example - where are they today?
Well, they'd have to start all over again! Since that was over 40 years ago and the economy was still okay, hopefully they achieved much of what they lost and learned some HARD lessons about how not to listen to foolishness spouted by religionists.
I joined after 1975 and not a word was mentioned to me about this massive failure of theirs. Thankfully, I ignored their bullshit and held onto MY job.
I hope history doesn't repeat itself but sadly there will be gullible Witnesses who fall for the old "sell your stuff, quit your job and pioneer."....
