were to be used to motivate the labor force, including allowing peasants to earn extra income by selling the produce of their private plots at free market. Rural markets selling peasants' homegrown products and the surplus products of communes were revived under the more free-market economic approach of Deng. Not only did rural markets increase agricultural output, they stimulated industrial development as well. With peasants able to sell surplus agricultural yields on the open market, domestic consumption stimulated industrialization as well and also created political support for more difficult economic reforms. Development remains uneven, with many highly prosperous areas far outpacing deeply impoverished regions where parents have great difficulty attaining enough income to ensure their children can be sent to school, despite the already-low education fees. Indeed, educational and social imbalances are a salient feature of this uneven development. One emerging trend since at least the 1990s is the "floating population" or "black (e.g. black market) people", rural migrants (民工 min gong) entering urban areas in search of work. Until recent developments, rural residents lacked the legal permission to resettle in urban areas without approval, yet between tens and hundred of millions did resettle in search of jobs. Many have found work, in the form of construction and other sectors with relatively low wages and benefits, and high workplace hazards. Numerous social issues have developed as a result, namely discrimination of ruralites in cities, psychological isolation of rural migrants, some of which has led to crime. In this sense, then, rural life has "entered" the cities. Lack of employment opportunities has increasingly made life in many rural regions difficult, hence the apparent enticement to resettle in urban areas. Of course, jobs are still limited, so many do relocate in cities only to find prospects much more meager than they had expected. Statistics suggest a very high proportion of residents of rural areas are unemployed or underemployed. The development of Special Economic Zones also spurred rural growth in some parts of China. In 2013, China announced a new plan to reduce poverty and develop impoverished rural regions by raising rural farmers' income growth and reducing obstacles in agricultural development. The plan includes the promotion of new types of agricultural businesses, such as family farms and organized cooperatives, and encouraging industrial and commercial enterprises to invest in agriculture.
