Regulation in Broadband Access
The data lines that carry our internet traffic makeup part of the infrastructure of this country just like the concrete of the sewers and highways, and infrastructure is an area - an inefficient market - that requires government regulation and funding to be both competitive for its (usually) small number of companies and fair for the public that needs access to it.
Larry Lessig has a good post about how the United States is falling behind the rest of the developed world in internet infrastructure development because of a lack of intelligent regulation in the broadband access market.
