Jonah Goldberg makes a conservative critique of populism:
Politics has a math of its own. Whereas a scientifically minded person might see things this way: One person who says 2+2=5 is an idiot; two people who think 2+2=5 are two idiots; and a million people who think 2+2=5 are a whole lot of idiots-political math works differently. Let’s work backwards: if a million people think 2+2=5, then they are not a million idiots, but a “constituency.” If they are growing in number, they are also a “movement.” And, if you were not only the first person to proclaim 2+2=5, but you were the first to persuade others, then you, my friend, are not an idiot, but a visionary.
Of course, idiocy and its distribution in the population isn’t the point. You can build a movement out of true observations-i.e. 2+2=4-as well. The point is that political power flows from numbers and, more importantly, that such power becomes self-justifying for those who enjoy its effects. Passion becomes more “legitimate” as more people share it, no matter what the content or object of that passion is. Any unified field theory of politics would have to include this basic law of the political universe. It is true in democracies and dictatorships alike. Like the laws of gravity or thermodynamics, it can be exploited or minimized. But it cannot be repealed. It is a constant of the human condition.
I suggest reading the whole article, but here are a few excerpts I particularly enjoyed:
From the mobs storming Versailles to the Banana Republic dictators seizing the oil fields, populist programs have been based as much upon grasping envy and narcissistic resentment of those who “think they’re better than us” as on any sort of principle. It’s not just that populist arguments are most often arguments in name only. They are sharp rhetorical sticks poked in the eye of those with little to lose and much to gain by overturning the board when the rules work against them. Individual responsibility gets lost in a swamp of whininess about what others “owe” the people. When Homer Simpson ran for sanitation commissioner, he captured the populist pose perfectly: “Animals are crapping in our houses and we’re picking it up! Did we lose a war? That's not America! That's not even Mexico!”
... it is in this gray area where I think conservatives should maintain a healthy, rather than absolute, skepticism toward populism. It is the first duty of conservatives to say “that’s not a good idea” and “calm down.” It is the first duty of liberals to come up with some whacky idea about how every child should be born with an air hockey table and a lifetime supply of Ho-Hos. When life is unfair to some, we can expect the liberal to blame dark and unseen forces rigging the system against the little guy. It is the conservative’s obligation-when the truth is on his side-to say “lighten up Francis” and “life isn’t fair.” And when would-be voices of the people claim that 2+2 is whatever-the-hell-we-say-it-is or that “the man” should be cleaning up our pets’ messes, it’s the job of the conservative to calmly say-no matter how unpopular or “unenlightened” it may be-no, 2+2=4, now and forever, and pick up your own damn crap.
