". . . the rise of the social-welfare state was a response (often of market-oriented liberal democracies) to the threat of popular revolutions, socialism, and communism as the frequency and severity of economic and financial crises increased . . . Any economic model that does not properly address inequality will eventually face a crisis of legitimacy. Unless the relative economic roles of the market and the state are rebalanced, the protests of 2011 will become more severe, with social and political instability eventually harming long-term economic growth and welfare."
