In the JWs, just as in the real world, there are the haves and havenots. There are those that want more and there are those who are satisfied with their lot in life. There are those who are well-to-do and there are those trying to get out of poverty.
It is interesting, though, to see how people were treated based on their position in the congregation. Elders that had money, nice homes, nice cars never seemed to suffer the guilt trip of being warned about materialism, but let a regular publisher, you know, the guy who gets 8 hours of service a month, misses a handful of meetings a month, doesn't help at quick builds, spends time with worldly family, etc, let this guy come into a little money and get a bigger house or a new car/truck and all of a sudden the elders are anxious to "help" this brother "avoid the snare of materialism".
I know, I'm one of em. We struggled the first few years of our marriage to make ends meet. Not one word of encouragement about how the friends would be there to help if we needed them, but we were admired for always "putting Jehovah first". After a few years, our jobs changed, our incomes changed and we were actually doing pretty good. New house, new cars, new furniture, new toys, etc. Then the friends started looking at us a little different. We were "different" somehow. They didn't seem to trust us. The elders were "concerned" about our new found "wealth" and how it "might" be detrimental. I lost count of how many people made comments about "why did we need THAT car" or "why such a big house" etc.
I used to be a little embarrassed by our good fortune to be able to afford what we have, because of the attitude of so many at the hall. Over time (and as I faded away) I have realized that we have worked hard for what we have and I owe no one an apology for where I live, what I drive or what I do with my money. If a JW, elder or otherwise, questions it, I will be quick to tell them to mind their own business.
