I was never one of the 'in-crowd', in any of the congregations I went to. I never strove for positions (privileges), never was a pioneer (but auxiliary once or perhaps twice), and basically never believed in myself. Never had a study, probably for that reason.
And still I would sometimes leer ["leer" may be the wrong word; it was the best I could find on 'short notice'] at people coming late to the meeting, people not in good standing, people who had been DFed and just been reinstated, people only coming in for the memorial, etc. Today I hate that I would once think or act like that toward others.
I think that in any group of people where you can strive for 'perfection' and to earn 'privileges', there will be some who do well and others not so well, and you will get a class system eventually.
