Political scientist John Sides has contributed an interesting guest post to FiveThirtyEight, in which he reviews the evidence that social class influences the way Congresspeople vote. In particular, Congresspeople are unlikely to come from working-class backgrounds, and class seems to affect voting at the individual level. If Congress had the same mix of class backgrounds as the general American public, they would in general be slightly more liberal.
My first reaction was: I wonder how much of this reflects IQ. Intelligence makes people think like economists and also increases people’s income and probably shifts class background toward mentally intensive occupations.
My second reaction was: Assuming the result stands, do we want Congress to reflect the same background as the American public? Should everyone be represented equally? It’s not obvious to me that they ought to. I’m on record here as supporting limiting in some way the right of government employees and contractors to vote. Even if you don’t share my libertarian proclivities on public policy, however, a slightly upper-class-tilted public policy regime might be desirable for straightforward reasons of stability. In a pure democracy that is strictly responsive to the median voter, businesspeople and professionals might become alienated from democracy itself. That may sound like a bit of a stretch for the United States, but not for many countries around the world where upper-class opposition to democracy has entrenched electoral fraud, clientelism, or military supervision of civilian authority.
