That old insular thing of hiring your own makes it incumbent on the tribe to ensure members are competent.

Still a lot of businesses operate this way. Even now with my new job, I feel like they don't really care about competence that much. As long as I'm part of their tribe or that I agree with them 100% all the time. Even big businesses lose money this way because this old behavior of their managers still persists. They lose the talented and keep the incompetent.
