Command line admins are expensive. GUI admins are cheap.
It costs a little more to get someone who knows why they're doing what they're doing.
I thought the whole point of GUIs was, you didn't need no stinkin' admin.
Seriously, to admin efficiently, you need copious automation. A GUI layer on top of the automation is fine and dandy. But the admin needs to understand the automation, so he can can cope when it breaks and upgrade it to meet changing needs. Such admins are not cheap.
