This, except the the lever doesn't actually control which track the trolley goes down, that is controlled by the trolley corporation. The third track is being built by people who understand this, in order to connect it with the other tracks so that noone has to be run over, but the person pulling the lever thinks they are pulling the track-switch.

The trolley corporation rigged it so that when the person pulls the lever, it actually bombs the other track, so that it won't connect to the rest of the tracks, killing a few track builders in the process. The lever puller is told by the trolley corporation that the track would have switched except the track builders are terrorists who blew up the switching mechanism because they hate freedom. But not to worry, keep pulling the switch because it is actually individual switch pullers, not trolley corporations, and definitely not track-building "terrorists," who make all the decisions, and that switch pulling is a sign of a healthy and civil society.
