All the studies I have seen make it clear that the LDS Church membership as a whole is one of the best educated, most financially well off of any Christian denomination - especially after the second or third generation in the Church.
That's not a boast. It's not good or bad, imo - except to be good in the sense that it enables the Church membership as a whole to give enough to self-perpetuate. That's a good thing. However, general prosperity can lead to pride and a focus on money - and our canonized scriptures are replete with examples of what can happen to communities in that condition.
As I have said in numerous settings, I actually do believe in the general concept of communal prosperity through dedication, hard work and "goodness". It's when that general prosperity gets conflated with individual prosperity, and when individual wealth and individual poverty become markers of worthiness and goodness that it becomes a problem - and, unfortunately, that is a very natural human tendency in all communities and groups.
Professional athletes are admired and revered by many. Why? They are rich.
Movie stars are admired and revered by many. Why? They are rich.
Business tycoons are admired and revered by many. Why? They are rich.
At least in the Church, many local leaders (and General Authorities, for that matter) are not rich - so that should mitigate the natural tendency. It does for many, but it doesn't for others. That's not an indictment of the Church, in my opinion, but rather a statement about how strong our natural tendencies are.
