So says Robert Wright. Excerpt:

The new information technology doesn’t just create generation-3.0 special interests; it arms them with precision-guided munitions. The division of readers and viewers into demographically and ideologically discrete micro-audiences makes it easy for interest groups to get scare stories (e.g. “death panels”) to the people most likely to be terrified by them. Then pollsters barrage legislators with the views of constituents who, having been barraged by these stories, have little idea what’s actually in the bills that outrage them.
It’s no exaggeration to say that technology has subverted the original idea of America. The founders explicitly rejected direct democracy — in which citizens vote on every issue — in favor of representative democracy. The idea was that legislators would convene at a safe remove from voters and, thus insulated from the din of narrow interests and widespread but ephemeral passions, do what was in the long-term interest of their constituents and of the nation. Now information technology has stripped away the insulation that physical distance provided back when information couldn’t travel faster than a horse.
It’s no exaggeration to say that technology has subverted the original idea of America.
I don’t see a miracle cure here. It would be hard to restore much of the insulation without tampering with the First Amendment.
