The latest issue of Macleans Magazine (the Canadian equivalent of Time Magazine) has an article on the increasing isolation of not only Americans, but Canadians and Britons as well. People increasingly live in communities where income levels, jobs, interests, and especially political views are nearly identical. In Washington, D.C., there are very clear Democrat neighborhoods and Republican neighborhoods where the only differences between the neighborhoods are political views and allegiances. The article says this trend actually began in the 1970s with the widening availability of automobiles and the ubiquity of telephones, and the internet has exacerbated the phenomenon instead of causing it. The polarization of American politics, the article says, is ultimately caused by people retreating to echo chambers where everyone agrees on everything. In the past, greater interaction with a wider variety of neighbors foced people to compromise and come to a consensus, but that has gone out the window, and the politicians have become strident and uncompromising to reflect the views of their constituents.
