I believe the socio-economic status of the elder depends on whether he developed any skills before entering the truth.
Or the status of their parents. The ones I mentioned above, who are a photographer and a businessman, were raised as Witnesses.
You can't tell me you've known an elder or a pioneer going to night school.
I've known of several young people pioneering while going to college. I have a good friend who had a part-time job opportunity that required a Masters, so she got the degree, got the job, and started pioneering.
I agree, however, eldering or pioneering, however, doesn't allow a person time to pursue continuing education while supporting a family.
An entrepeneur who enters the truth is a rare thing. A JW who becomes an entrepeneur while in the truth is almost impossible.
Let's see. My father started several succesful business of his own as a JW elder. I know several brothers who've established consulting practices after becoming JWs. And of course, you have the local cleaning moguls.
The fact is, the economic reality of being a JW depends heavily on the territory of the congregation. I just don't think you can make broad stereotypes.
