In North Korea, the state can simply send you to labor camps for no reason, where you risk your life fighting fires of making license plates for literal pennies per hour. You must do this because the state does not provide any living essentials such as hygiene items, medical care, or real food.
And then when your labor camp sentence is done, they just jail you again for no reason as soon as you walk out the door. This is considered normal and the people accept it.
