It’s the trolley problem. You see a trolley about to kill 5 people. You can pull a lever (vote) and make the trolley only kill 1. In this case, that 1 person is also in the lineup of 5. This distinction makes it obvious the only option is to pull the lever (vote).
Not voting doesn’t do anything but make you feel better about yourself. No one in power cares that you didn’t vote. They actually love low voter turnout because it’s an easier demographic to hit
