Charles Krauthammer‘s latest column explains how our 44th president is playing a similar role for the ideological left to the role our 40th president played for the right. Krauthammer focuses on the themes of President Obama’s second inaugural address.

It was a paean to big government. At its heart was Obama’s pledge to (1) defend unyieldingly the 20th-century welfare state and (2) expand it unrelentingly for the 21st.

The first part of that agenda — clinging zealously to the increasingly obsolete structures of Social Security, Medicare, and Medicaid — is the very definition of reactionary liberalism. Social Security was created when life expectancy was 62. Medicare was created when modern medical technology was in its infancy. Today’s radically different demographics and technology have rendered these programs, as structured, unsustainable. Everyone knows that, unless reformed, they will swallow up the rest of the budget.

As for the second part — enlargement — Obama had already begun that in his first term with Obamacare. Monday’s inaugural address reinstated yet another grand Obama project — healing the planet. It promised a state-created green-energy sector, massively subsidized (even as the state’s regulatory apparatus systematically squeezes fossil fuels, killing coal today, shale gas tomorrow).

The playbook is well known. As Czech president (and economist) Václav Klaus once explained, environmentalism is the successor to failed socialism as justification for all-pervasive rule by a politburo of experts. Only now, it acts in the name of not the proletariat but the planet.

Monday’s address also served to disabuse the fantasists of any Obama interest in fiscal reform or debt reduction. This speech was spectacularly devoid of any acknowledgment of the central threat to the post-industrial democracies (as already seen in Europe) — the crisis of an increasingly insolvent entitlement state.
