A history lesson for Democrats on Paul Ryan's budget

Liberals think Medicare and Social Security as they exist are “fundamental” to the nation’s identity. But liberals think the Constitution — which the Framers meant to be fundamental, meaning constituting, law — should be construed as a “living” document, continually evolving to take different meanings under whatever liberals consider new social imperatives.

The lesson of all this is that one’s sense of possibilities — and proprieties — is shaped by what we know, and often do not know, about history. The regnant ideology within the Obama administration and among congressional Democrats is reactionary liberalism, the conviction that whatever government programs exist should forever exist because they always have existed. That is, as baby boomers, in their narcissism — or perhaps solipsism; or both — understand “always.”
