North Korea's economy operates under the Democratic People's Central Bank and remains one of the last centrally planned systems centralized in the world. North Korea has a command economy based on agriculture and natural resources. The government allows private farmers' markets to sell a range of products, and it also allows some private farms on experimental land. Although agriculture plays a less and less important role in the national economy, there has been an increase in cropland projects, mechanization and the use of chemical fertilizers. Farmers are either paid or allowed to raise bees, fruit trees, chickens and gardens. Some farmers can sell their leftover produce at regional markets that take place every year. Farmers fare better than most urban workers during lean years, but they still struggle to survive. In North Korea, barley, cereals, corn, wheat and rice are the main food crops. They also grow potatoes, sweet potatoes, soybeans and other orchard vegetables and fruits. Their industrial crops consist of flax, cotton and tobacco. Areas that fail in cultivation are used for livestock farming. The sea is where North Koreans get most of their protein. The main marine species caught are shellfish, yellowtail sardines, pike, herring, pollack, sardines and mackerel. North Korea has a wealth of natural resources and its terrain is mostly hilly and mountainous. They have a large amount of mineral deposits, it is estimated that around 200 minerals have economic value. The main ones are iron ore and coal, the most important being magnesite, zinc, lead and gold which led to extradition. They also contain a lot of tungsten, barite, graphite and molybdenum. Electricity production is mainly based on hydropower, but the middle of paper is contradictory, but even though there is no minimum wage in 2002, the government has carried out price/wage reform. The state provides free health care, education, food rations and housing. Although there is health care in the hospital, patients must pay for their own medications, prepare all their meals at home, and cover heating costs. The average worker earns about $2.00 to $3.00 per month from the government, some people work on the side selling goods in local markets and earn about $10.00 more per month. About half of North Korea's population lives in extreme poverty. People who are really trying to survive live on kimchi and corn and have limited access to fuel for cooking and heating. Kim Jong Un is worth $5 billion, most of the money comes from counterfeiting, government businesses as well as the sale of narcotics and other types of crime..
