That liberals wish libertarians to go away is, perhaps, not surprising. But the issue is much more serious than even Jonah Goldberg realizes. McCain's championing of "getting the monied interests out of politics" and Obama's pledge to eliminate their influence both amount to an attempt to eliminate economic interest groups (and, indeed, interest groups that are in any way allied with economic interests - such as independent free market groups) from politics. But, politics is about interest group influences. If economic interest groups are eliminated, only ideological groups are left - right and left groups driven by cultural, ethnic, environmental or other religious values. Is that world likely to prove more tolerant, more compassionate, more "concerned?"
My personal vision of the future is to find myself about to testify in Congress on some creative expansion of the state. As I'm about to testify, the chairman speaks up: "Mr. Smith, before you begin, I have a question I'd like you to answer. Are you now or have you ever been associated with the wealth producing sector of the United States?"
A world where economic interests are disenfranchised - indeed, even de-legitimized - is a world that will have little regard for economic - and, thus, indivdiual - liberty.
Ideologues have created far more horrors than have even the most rampant of business villains. My understanding is that Stalin, Hitler, Pol Pot and Mao Tse Tung were not motivated by profits.
