"Some of the salariat have joined the third group, ‘proficians’, those with bundles of technical and emotional skills that allow them to be self-selling entrepreneurs, living opportunistically on their wits and contacts. This group is growing but is relatively small; it tends to be socially liberal but economically conservative, since it wants low taxes and few obstacles to money making.
Below the salariat and proficians in terms of income is the old manual working class, the proletariat, which has been dissolving for decades. The democracy built in the twentieth century was designed to suit this class, as was the welfare state. Trades unions forged a labourist agenda and social democratic parties implemented it. That agenda has little legitimacy in the twenty-first century.
Below the proletariat is the rapidly growing ‘precariat’, a class-in-the-making." (http://www.opendemocracy.net/guy-standing/precariat-why-it-needs-deliberative-democracy)
