2. Social ecologists argue for a decentralized society of communities, modern in technology and wise in environmental husbandry. They blame exploiting classes and interests for the ecological mess. Their worldview embraces outcasts and refugees from the present capitalist economic system, such as travellers, squatters, unemployed and other societal drop-outs, arguing that work does not necessarily depend on formal employment and status. It encourages exchange of services and goods without money (the black economy). For social ecologists, deep ecology is as so much middle-class "ecolala", spiritual striving and philosophical escapism which avoids the issues of how people live on a daily basis.
