The poorer the locality the greater the chance of this activity would probably occur.
I can remember going to halls in the most richest of areas and halls in the most poorest of areas and I did notice a difference in peoples social behavior
Funny as it is the last personal encounter with a JWS was a fellow that was involved with off shores money investment schemes , much like a mLm or a pyramid scheme
I'll let you know I did not take him up on his offer although he sure tried hard , further in the sales pitch it came out that he was to receive a money kick back
if he could get me signed up.. Apparently a few months latter my brother tells me that his same guy lost $20,000.00 on this scam which he also tried to sell to my brother
a true JWS idiot !
