No, they're not. Even if something bad is somewhere in an origin story, that doesn't taint the existence of a thing. Most of the complaining about suburbs comes from people who want people to live bunched together, ant-like lives. Should there be more room for small businesses in and around suburbs? You bet. Encouraging walkability, not having to drive forever to get groceries, etc., is useful. But this push to take away the freedom of people to not live on top of each other is another form of classism, one oriented toward the imposition of suffering rather than toward encouraging freedom.
