In the last 20 years, the idea that the social realm is under threat of decline or collapse has been a central theme in academic literature and political analysis. In this short paper I explore the meaning of social decline and its relationship to multiculturalism and diversity. Using the twin notions of participation and trust as two key measures of social decline, I argue that participation has not so much declined over the last 40 years (as Robert Putnam, for example, has argued) as it has changed because of what I call the politics of the us's groups historically oppressed (including women, ethnic and racialized minorities and gay, lesbian and disabled citizens) who have created new kinds of advocacy organizations in order to change the norms of civil society itself. I also argue that such changes (while often perceived as negative in relation to a transcendent "us") are positive to the extent that they have made society more inclusive, respectful of diversity and just. Trust, on the other hand, has declined but, 1 argue, this is also due to the politics of diversity as the us's fought for change and other groups responded by defending traditional norms and values, often in the name of a transcendental us, creating a vicious circle of distrust as each side feels betrayed by the other's victories. Thus, I conclude, to understand social decline, in terms of participation and trust, we must pay attention not only to the us but also to the us's in civil society. The tendency, therefore, to champion a transcendent us in order to reverse social decline, as many scholars and politicians seem prone to do in recent years, not only ignores the us's but may foreclose on their hope for a future free from discrimination and hate.
