Because that is one thing i know that people mention a lot in moving to cities. Maybe part of it is american perspective. Is there something WRONG with talking about multiculturalism? eg. gay people leaving their small towns that don't have other gays, immigrants moving to a city full of people of their nationality (eg. "china towns, little italy"). No amount of "is renting forever not bad?" will rectify this advantage of a city for many people.
