From Yuval Levin's essay of the above title:
...this vision has never been implemented in full. But it has offered a model, for good and for ill. For the left, it provided long-term goals, criteria for distinguishing progress from retreat in making short-term compromises, and a kind of definition of the just society. For the right, it was a foil to be combated and averted — an archetype of soulless, stifling bureaucratic hubris — and it helped put objections to seemingly modest individual leftward steps into a broader, more coherent context. But both ends of our politics seemed implicitly to agree that, left to its own momentum, this is where our country was headed — where history would take us if no one stood athwart it yelling stop.
It is no longer really possible to think so. All over the developed world, nations are coming to terms with the fact that the social-democratic welfare state is turning out to be untenable. The reason is partly institutional: The administrative state is dismally inefficient and unresponsive, and therefore ill-suited to our age of endless choice and variety. The reason is also partly cultural and moral: The attempt to rescue the citizen from the burdens of responsibility has undermined the family, self-reliance, and self-government. But, in practice, it is above all fiscal: The welfare state has turned out to be unaffordable, dependent as it is upon dubious economics and the demographic model of a bygone era.
