Ahhh now I see...  Network B is actually carrying ~25x the traffic for a
given flow.....  Thus is costs them 30x as much for the cross-country
piece, and thus Network A should in some way help out with the costs.

Of course this gets really interesting when you start thinking about what
kinds of implications this kind of thing can have in the long term.  When
Network B demands that Network A pays a settlement, Network A will
obviously want to find a way out of it eventually.  To do that, Network A
drops it's pricing for customers that 'suck' a lot of bandwidth to balance
out their traffic and avoid the settlement fees.  Those customers that
'suck' are most likely the customers of Network B in the first place that
Network A is now targeting.  So in the end, Network A ends up creating a
lot of downward price pressure on themselves!! 

Believe me, this is not just a theory, I've been involved with this exact
situation from both the backbone and the transit purchaser side, and this
is really happening.  It's somewhat ironic, but it seems that the cost
model for the Internet is moving towards a sender pays model.
