Which numbers are you referring to? The numbers I quoted are what I pay as direct costs... The cost of regulation is another matter entirely, but even then there are also subsidies offered left, right and centre in some areas which can counteract some or sometimes most of these costs.
For providers offering phone service, there's usually between $5 and $10 on top of the advertised monthly rate that's taken directly from the subscriber as "taxes and fees" for stuff like 911 (which I think is absurd - other countries manage to fund their emergency numbers just fine) - we have something like 8 line-items on our invoices IIRC, it's ridiculous.
As far as other costs are concerned, the franchise agreements in some cases give almost free reign over the rights of way so there's not really any additional payment or differing rates as I understand it, it's just one big bulk thing - in my case, I'm in a Mediacom town and I've seen some really shitty cabling on their part (including stuff run across the ground and just left lying there for what has now been... 4 months?), yet, we got bitched at for having a cable secured in a slightly incorrect way which was 1. temporary (72 hours) and 2. was actually secured to the surface and, we believe, less of a hazard than some of what we've seen. Of course, we don't have a franchise //yet// either.
I deal almost exclusively with smaller towns though so my situation may not be representative of what happens in larger cities - I can imagine those being a complete bitch simply due to their size and the extra layers. I do agree, however, that the "playing fields" **should** be level, monopolies should be absolutely verboten and as above, that all infrastructure should be shared with any licensed provider who wishes to use it (the latter would probably prevent some of these mega-mergers too).
