Modern liberalism is a mixture of two elements. One is a support of Federal power – what came out of the late 1930s, World War II, and the civil rights era where a social safety net and warfare were financed by Wall Street, the Federal Reserve and the RFC, and human rights were enforced by a Federal government, unions, and a cadre of corporate, journalistic and technocratic experts (and cheap oil made the whole system run.) America mobilized militarily for national priorities, be they war-like or social in nature. And two, it originates from the anti-war sentiment of the Vietnam era, with its distrust of centralized authority mobilizing national resources for what were perceived to be immoral priorities. When you throw in the recent financial crisis, the corruption of big finance, the increasing militarization of society, Iraq and Afghanistan, and the collapse of the moral authority of the technocrats, you have a big problem. Liberalism doesn’t really exist much within the Democratic Party so much anymore, but it also has a profound challenge insofar as the rudiments of liberalism going back to the 1930s don’t work.
This is why Ron Paul can critique the Federal Reserve and American empire, and why liberals have essentially no answer to his ideas, arguing instead over Paul having character defects. Ron Paul’s stance should be seen as a challenge to better create a coherent structural critique of the American political order. It’s quite obvious that there isn’t one coming from the left, otherwise the figure challenging the war on drugs and American empire wouldn’t be in the Republican primary as the libertarian candidate. To get there, liberals must grapple with big finance and war, two topics that are difficult to handle in any but a glib manner that separates us from our actual traditional and problematic affinity for both.
