What the other replies said to this guy about average vs local density is perfectly correct. But even in low density areas, this is STRICTLY an upfront capital issue. Only the original install costs much more. The increased service delivery cost once you have the larger amount of fiber per customer installed is barely worth discussing except for the accountants who finally figure out that the US suburbs should be paying 1.87 cents per GB rather than 1.74...it would be those kinds of numbers.
The article says it plainly: in dense apartment areas, $280 per install; US housing, $2200. But really, what's $2200? A one-time investment that pays off over what, 40 years? The copper lines to my house date to 1954, the TV cable to 1973. The asset lifespan exceeds the 40 year max that even a large utility can get to pay down an investment. So even with interest (which these days is tiny, by the way, but lets use 4%), it's about $100/year added to your bill to pay off your install, unless you want to pay up front.
God, it's such a crap argument in so many ways - so unworthy of a nation that was among the first to bring in electricity and then phone and then cable, the last especially to provide so much less utility (57 channels and nuthin' on...) than Internet...but it comes up every time. That 57 channel TV cable was DONE, jack, between about 1970 when I first heard talk of it, and 1980 when everybody had switched to it. Here we are 20 years after everybody started wanting on the Internet, and virtually no new lines strung, they're still using the 1930s phone wires and the 1970s TV cables that were already paid for...but charging you like they had.
The people making these excuses for them are among the robbed, and they should just stop.
