I knew of only a few "educated" elders, in that they had college degrees and had a "career" that was based on their education. Of these elders, they were barely elders. They were so busy with family and career, they really didn't go out of their way to do any more than they had to in the congregation. They were usually easy to like and were not vindictive or cruel when it came to dealing with those that got in trouble.
Most of the elders that I knew had high school educations and had either factory jobs, construction jobs or were self-employed in construction, cleaning, etc. Out of this group came both the kind, merciful elders and the self-righteous, sanctimonous elders. There didn't seem to be any coorelation between income, education or status in the "world" and they're being a good elder or not. Some were good, some weren't so good and others were rotten. The ones to watch out for were men who relished the power of being in charge and loved to lord it over people.
