Yet Korea's internet infrastructure is a fair bit more regulated in comparison to ours. One of the biggest reasons why internet penetration has become to widspread and well developed there is because the government took an active interest in it.
Though it does have downsides, such as a complete lack of internet anonymity.
Our copper infrastructure is under a lot more price regulation. Verizon, one of the main opponents of net neutrality, had no incentive to build up their existing copper network to support faster DSL, the way Korean telcos did, because they would not have been able to reap the financial benefits of doing so. "Renzatic Virtual Carrier" or anyone else could have demanded access to the last mile connection at rates that wouldn't justify the investment (since DSL operates best over short distances). Hence the reason that they, AT&T, and others invested in fiber optic. Those networks, up to now, have been exempt from the Title II regulations.
Our fiber optic networks are just as fast as in any other country. However, they aren't as widespread since the telcos had to start from scratch, and had a lot more territory to cover than, say Korean companies.
The other disincentive has been state and local governments striking essentially monopoly deals with telcos to freeze out competition. What's needed is more competition by getting rid of these sweetheart deals, rather than more regulation. The problem with highly regulated entities is that they have little incentive but to meet the bare minimum the regulators require.
