Besides, having read the history of Athens, direct democracy can be described as mob rule, and there the problem of 51% of the population votes to kill off the 49% others was a very real problem. Every American probably can imagine the problems guilds created in medieval Europe, right ? Athens was a state where the equivalent of guilds could literally and legally decide to kill the competition (which they did, several times).
Besides, let's not lose sight of reality here. America would be a near-theocracy if it was a direct democracy.
Switzerland seems to work pretty well by direct democracy.
I do recall reading up on that recent referendum they had about the capping of CEO wages that didn't go through. But thanks for the heads up, I'll look into what they have going on over there with their flavor of democracy.
Forget money as some sort of concept that breaks democracy by allowing people to game the system. The bigger problem you have to worry about is the smooth-talkers, the influential leaders and all their legions of followers. Their single influential vote, counts a whole lot more than yours, or ours, and that single vote means no equality.
