You are right in your observation that people in the religion, in general, have serious issues of jealousy over anybody who looks like they are doing well. Whether this is an illusion or not isn't even the point. Sometimes a person puts on a brave front and presents themselves well in public, but that doesn't mean all is well. Such a person would be the last person to be helped by the congregation. As you mentioned, to add insult to injury, it also has to do with how well somebody "performs" in the religion.
As far as 'poor' JWs suffering for righteousness sake, I remember going out in service years ago in a well-to-do area with a struggling couple who made remarks that the people in these houses "were having their reward in full". I thought to myself how cruel and jealous this sounded.
