my take on people with money is that they have learned how to do things and how to get things done.they know how to play the game.
therefore they have worked out that generally in life people are taken more seriously if they are not beligerent or overly demanding and so go about their days with a quiet but confident manner.
such people are not necessarily any more genuine than someone of little means but looks are important.
From my experience it seemed that brothers who had successful secular careers and were financially secure, not rich, but comfortable showed a more confident look than many of the down trodden folks. From how they dressed to what they drove, they exuded a confident style not always seen in less privileged ones.
The other elders noticed it and acted accordingly.
There was usually a poor brother who knew more about the Bible, was well versed in JW doctrine and was loved by all but he couldn't be counted on to show up on time for service because of his broken down old jalopy or he had to deal with some other issue that other people would have hired to be done. Because of that stigma of being poor, he would be overlooked for a position while Brother Career would be picked to serve, not because of his knowledge or love of Jehovah, but because it appeared that he had his sh*t together and could be counted on to carry his share of the load.
