I've often thought that is is one of the principal reasons that there is still explosive growth in the Hispanic congregations in the US.
Imagine someone who grew up in a hovel in rural Mexico, no running water, no electricity, chickens running around on the dirt floor of the kitchen...
He makes it to the US, but he gets the crummiest, most dangerous job imaginable because he needs the money...
Now here comes Jason & Suzy Need-Greater, who stumblingly stutter through a barely-undrestandable magazine presentation. But the target somehow perceives they are talking about the Bible, which he has great respect for, and so takes the magazines...
The return visit is handled by someone who speaks the language better, and soon a study is started, and he starts attending the Kingdom Hall...
Imagine what he thinks the first time he attends a District Convention...he sees 10,000 people, most of whom from origins like his...and there's someone who grew up 10 miles from his home, well-dressed, giving a Bible discourse and thanked with extended applause by 10,000 adoring attendees. After the session the speaker is surrounded by well-wishers, all anxious just to be seen near him.
And his study conductor says, "One day, if you do well, you too can be an elder and give talks at the assemblies".
How else is Jose going to get that kind of recognition? What other organization offers him so much - eternal life, the chance to see his dead gramma, and until that day arrives, the chance at being respected, liked, and fitting in?
