The threat of groups out of the normal population correcting them, or in worst case firing them, for not kept promises or derailing plans, can keep them from seeing the population as nothing more than numbers and themselves as a superior in-group.

That's why i think that Swiss' initiative/referendum right is a prerequisite for a longtime-stable democratic system. I often see that in germany, where politicians do what they want and people complain that they lie in elections anyway. While here, even the president can take the bus to the Bundeshaus.
