Writer and ironically self-described "brain-dead liberal" David Mamet has written a compelling account of his transition from "liberalism" to realism.
Prior to the midterm elections, my rabbi was taking a lot of flack. The congregation is exclusively liberal, he is a self-described independent (read "conservative"), and he was driving the flock wild. Why? Because a) he never discussed politics; and b) he taught that the quality of political discourse must be addressed first—that Jewish law teaches that it is incumbent upon each person to hear the other fellow out.
And so I, like many of the liberal congregation, began, teeth grinding, to attempt to do so. And in doing so, I recognized that I held those two views of America (politics, government, corporations, the military). One was of a state where everything was magically wrong and must be immediately corrected at any cost; and the other—the world in which I actually functioned day to day—was made up of people, most of whom were reasonably trying to maximize their comfort by getting along with each other (in the workplace, the marketplace, the jury room, on the freeway, even at the school-board meeting).
And I realized that the time had come for me to avow my participation in that America in which I chose to live, and that that country was not a schoolroom teaching values, but a marketplace.
"Aha," you will say, and you are right. I began reading not only the economics of Thomas Sowell (our greatest contemporary philosopher) but Milton Friedman, Paul Johnson, and Shelby Steele, and a host of conservative writers, and found that I agreed with them: a free-market understanding of the world meshes more perfectly with my experience than that idealistic vision I called liberalism.
I highly recommend reading the whole thing. If you're a leftist you might find some new ideas to consider, and if you're not you'll at least get some insight into the "liberal" mind.
The disconnect between reality and the prevailing leftist view of a world gone horribly wrong that must be fixed immediately, by government, at any cost, is why I often have a hard time respecting even the most intelligent leftists I encounter. This cornerstone of leftist dogma just does not compute.
