Louis,

This isn't the place to debate your apparent general view that most  
waste and inefficiency can be explained by the profit motive.  But  
let's look at the specific case in hand.  The situation (as both of  
us describe it) would have the ISPs be able to reduce costs. (Whether  
they pass those cost savings on to the customer to increase market  
competitiveness or keep it as additional profit margins makes no  
different for this case, either way the ISPs benefit from providing  
NTP service to their customers).

It may be true that the big carriers want ISPs to behave wastefully,  
but that still wouldn't explain their behavior.  First of all, my ISP  
is a big carrier (Verizon).  So nobody with any influence on my  
connectivity has an interest in me (flat rate payer) wasting  
resources.  Second of all, a smaller ISP doesn't need to depend on  
its provider to learn about or implement NTP service.  Believe me, I  
had no encouragement from Verizon to use NTP properly, but still I do  
so.  Your claim would only make sense if the big carriers really were  
in a position to effectively withhold information about NTP from  
their customers (the ISPs).

So I am inclined to go with others' suggested answers to the puzzle.   
That ISPs figure that the cost of addition connections upstream from  
not providing NTP services for their customers is less than the cost  
(maintenance, support) of providing NTP services.

If that is the case, then it becomes harder to persuade the ISPs to  
"do the right thing".  But if it is just incompetence, then we have  
an easier task, since persuading them to do the right thing coincides  
with persuading them to do something that improves their profits.
