When you lose the New York Times on social liberalism, there's no more denying it: "Europeans Fear Crisis Threatens Liberal Benefits."
Across Western Europe, the "lifestyle superpower," the assumptions and gains of a lifetime are suddenly in doubt. The deficit crisis that threatens the euro has also undermined the sustainability of the European standard of social welfare, built by left-leaning governments since the end of World War II.
Nevermind that capitalists and conservatives have foretold this bit of bad news for half a century now, nor that the Times is far too generous in cushioning the news within the aura of mere "fear." European-style "social democracy" is failing (regardless of whether Europe fears it or not), and U.S. Democrats are on the verge of transforming America into the same unsustainable system.
This isn't a matter of learning from history - it's just a matter of looking out the window and being aware of the world around you. The sky really is falling, the wolves really are among the flock and the writing really is on the wall.
