Which is why bigger users get discounts on a per GB basis.  The
cost to the consumer has a fixed component which basically covers
the last mile, accounting etc. and variable component which covers
the cost of shipping the bits over the rest of the network which
is almost always over subscribed.  The difference between business
and residential reflects, or should reflect, the level of over
subscription and some penalty allowance to cover out of standard
hours repairs to meet SLA.
