Hello Grits,
There are considerable regional differences throughout the United States. The JWs like to think that they are very different and separate from the world, but the truth is that many of the things of the world are also the things of the JW community.
In certain areas many JWs are closer to or actually are professionally trained and educated. They bring this education to the KH. In many other areas, however, those attracted to the JWs are the more "humble" residents of the community. They many be nice folks, but by humble in this context I am referring to their lack of formal education. Their speech and reading skills are usually in keeping with their education and the environment in which they grew up.
Unfortunately, in some of the less well educated congregations, importing better educated JWs has not worked well (my experience in this area goes back many years and could be different today). The "old timers" sometimes have been jealous of the "imports" and have attempted to drive them away. Yes, even in the JW communities there are petty jealousies and resistance to change, even though the changes might be for the better and/or are directed by Brooklyn.
So much for separate and better than the world.
