They are *less* rare than Communism and Scrum done well, I've been in them (I've even been in a place or two that did Scrum well!), but yes, they are pretty rare.

Most companies, starting at the very top, are bad at evaluating talent, both on the hiring side and the retaining/evaluation sides of the equation, have zero training programs, don't have a mechanism for identifying and correcting mismatches (at best the mismatched is let go and the pain stops, at worst the mismatch is left in-place and causes problems for years and years and years... it's very rare to have a "ooops, this didn't work out, let's find something that better suits your talents" option)... there's a million things that go really wrong and when it's management/leadership positions, it's much more obvious and problematic than, say, a junior QA person or the HR person.
