It is obvious that the economic status of Jehovah's Witnesses and the Watchtower Society has changed in recent years. This is reflected in the prosperity of the Watchtower organization. One can only account for this by suggesting that many new converts brought a higher level of earnings and more generous contributions...or that a number of younger people in the organization ignored the counsel of the Watchtower and went ahead with their career plans anyway. In either case, it was not because the Watchtower encouraged people to pursue a lucrative career. But it is enjoying the fruits of this prosperity today.
The fact that JWs are still boasting about their properous brothers and sisters leads me to think that it is still important as a status symbol among its members. Does the rich man still get more attention and honor than the poor "brothers?" It used to be that way twenty years ago. And I dare suggest that it remains the same even today.
