In every congregation there are some elders that try to do their best, and there are also the big egos that put themselves above the others. Same goes for elderettes.
Unfortunately the organization promotes the differentiation of people based on their title, and on external appearances, and the ones at the bottom of the hierarchy become dependent and approval-seeking of the ones at the top, which contributes to the degradation of everyone as they become followers of men rather than followers of Christ.
Critizising the elders is like going against the holy spirit, the only unforgivable sin, so the simple sheep will think twice before opening their mouths against the arrangement. Not that many in the congregation will listen, after all nobody wants to be like rebel Korah and his followers that ended up being swallowed by the earth.
