There's a repeated mistake on this thread, namely people considering their costs when they price a job.
Do you really think about the cost of the components, assembly, shipping and retailing when you buy a phone (or anything else for that matter)? No, you consider value for money for you (not price), balancing what you're paying against what you're getting.
So the question is not whether someone's making an exorbitant profit or too little profit (or if they have to fund a new pole or if they use two broomsticks taped together), it's a matter of what the customer will pay for the level of service you offer.
If you just go in with a price, you're competing on one aspect of the deal. If you let the debate be just about price, you're stuffed unless you can cut service to the bone and go in lower than everyone else. If you sell yourself as offering an insured, well-mannered, super service with bells and whistles of some kind (up to and including a free prostitute for the day for the person buying), you can charge more because the value for money is there.
So, in short, there is no "correct" price for any job. There's just what someone will pay for the level of service you offer.
