Which costs more, wholesale, raw bitpipes or qualified
engineering talent to create/police the policies needed
to maintain QoS?

That's the $64k question. :-)
From what I've seen, there isn't a simple answer. In places where bandwidth
is exorbantantly expensive (such as outside the United States), simply over
provisioning isn't an acceptable answer. However, in some places in the
U.S. & Europe, over-provisioning may certainly make more sense. In our
area, we're also seeing a lot of pushback against the continued tearing up
of streets to lay additional fiber, so QoS may become the only option to
meet required service levels.
