Services provided by the private sector are affected as well. Average cost pricing for telephones, cable TV, gas and electricity, allows customers in low-density areas to pay the same fees for services even though it costs more to provide them there than in more efficient high-density areas. Another example of this is mail delivery -- think how much longer it takes to deliver mail to fewer people farther apart.

In other words, residents in high-density towns and cities, which typically have a disproportionate number of lower-income residents, in effect, subsidize the wealthier suburbs.
