Human rights in North Korea
Economic reform abolished the old coupon system in North Korea, which had favored non-productive citizens regarding access to food. After the coupon system disappeared, an average urban family spent between 75 and 85 percent of their income on food, while state farmers were spending only a third of their income on food. These disparities show that North Korea does not have safety net mechanisms to protect the vulnerable people in society, such as housewives and the elderly.
