The urbanized parts of the U.S. aren't behind in general. If the east coast states were countries, a number would be top-5 on Akamai's list for highest average bandwidth. As for HK and SK: there is only one city in the U.S. as dense as Hong Kong or Seoul, and that's NYC. And it has FIOS. So why does everywhere in NYC not have FIOS? Is it because of lobbying? No, its because building infrastructure in dense places requires coordination, and its just not a big political priority the way it is in Asian countries. Its why infrastructure projects of all kinds cost more in the U.S. from trains to telecom. In other countries, the government makes it a priority to remove roadblocks to infrastructure development, in a top down way. In the U.S., every infrastructure project becomes mired in NIMBYISM. Look in the back yard of Silicon Valley. Why isn't SF wired with gigabit. Is it because Comcast had more lobbying muscle than tech in tech's own back yard? Its an absurd proposition. The roadblock is instead the same dysfunctional government and the voters that complain about Google busses.

You're being downvoted because you're wrong. Density is a red herring that can be easily demonstrated by looking at comparative examples.
