Also, it's not just being "marginalized"; it's being SHRUNK.
From Wikipedia:
"The commons is terminology referring to resources that are collectively owned<1> or shared between or among populations. These resources are said to be "held in common" and can include everything from natural resources and land to software.<2> In some areas the process by which the commons are transformed into private property is termed enclosure.
"Concepts
"The commons were traditionally defined as the elements of the environment - forests, atmosphere, rivers, fisheries or grazing land - that are shared, used and enjoyed by all.
"Today, the commons are also understood within a cultural sphere. These commons include literature, music, arts, design, film, video, television, radio, information, software and sites of heritage. The commons can also include ‘public goods’ such as public space, public education, health and the infrastructure that allows our society to function (such as electricity or water delivery systems). There also exists the ‘life commons’, e.g. the human genome.
"The Ecologist (1996: 9)<3> refers to the commons as “the social and political space where things get done and where people have a sense of belonging and have an element of control over their lives”, providing “sustenance, security and independence”.
"There are a number of important features that can be used to describe true commons. The first is that true commons cannot be commodified – and if they are – they cease to be commons. The second aspect is that while they are neither public nor private they tend to be managed by local communities and cannot be exclusionary. That is, they cannot have borders built around them otherwise they become private property. The third aspect of the commons is that, unlike resources, they are not scarce but abundant (the Ecologist 1993: 9).<4> If managed properly, they work to overcome scarcity."
