"That's only a problem if there's a shortage of people with applicable skills" No, it's a problem to the discarded person, too, and potentially any future colleagues they might have worked with (or even hired/fired). Hiring and firing are not zero-sum games, they impact more than the just immediate individuals concerned. "If monoculture improves team effectiveness" This is a big "IF" in my eyes. Everyone going to the same bar to have a good time may be great fun, but isn't it nice to have some people who prefer other work hours who can start or finish something up for a team member in odd hours? Conversely isn't it nice for the odd-hour or solitary team member to have a more group-oriented colleague who can bring things to/from the solitary person to the group session? Etc... to other specifics.
