That was also a reason for the huge exodus after the failure of 1975. A lot of JWs would have probably let the failed prophecy thing slide by, but the fact that "servants" were now overseers, mass purges were taking place throughout the organization, and every congregation saw more JWs leave or fade away. JV2very insightful thoughts . look it up, the big exodus was not in autumn 1075, but when the change to slave drivers was instituted. A more profound stratifying of adherents than the clergy / laity model of BTG.
The word " serve" now is a corruption of the meaning, it should read "dominates", "governs" instead. the word "overseer" and "coordinator" does not even imply any service, work at all, only governance, with all it's prestige, entitlements , imho.
