They should keep in mind
They are overhead and customers are profit. If Judge Greene were still around, there would be broadband competition as he had the courage to break up the phone monopoly in 1984 and would do the same for broadband.
There will hopefully be a day where a judge will break up the internet monopoly/duopoly. The breakup of the phone company gave us choice of Internet in the 90's because the phone company acted as the pipes and ISPs delivered the content. Now that dial up is no longer usable and the phone lines can't support broadband and now the ISPs own the lines is what created the broadband monopoly. Now if we could subject cable/fiber to the same common carrier regulations as the phone, then we could have some competition. The problem is not that nobody is wanting to build new network infrastructure, it's that the incumbent carriers use their influence and power to snuff out competitors, just like AT&T did before Judge Greene broke them up.
All of my CPE (including my EMTA) is customer owned. The only Comcast owned equipment in my house is the CableCards in the two TiVO boxes I own.
What I noticed here is that AT&T must have built national network with taxpayers money. Did it begin in its first year of history with its own capital
If taxpayers paid for most of telecom infrastructure in this country, there should be no debate in congress whether to allow more or less regation. The problem is our system is corrupt, most politicians are just after quick bucks, take bribe and let the things the way they are.
In Poland, telecom lines were built by government owned tpsa. (TP), which later in 90's was privatized and sold to France Telekom. The prices went up, for everything but few years later, consumer protection agency broke tp's monopoly by mandating to share its pipes with other dsl providers at reasonable price. Within year or so over 50 dsl providers appeared in the market, prices went down. And dsl in this country was adsl2+ from beginning so it can support higher speeds up to 20 mb. Now they are in phase of deploying vdsl with speeds of 40 and 80 mb.
In larger cities cable providers like UPC offer high speeds already above 100, the highest now being 150 mb/s for less than Comcast's highest tier here in States.
