South Korean Prime Minister Han Seong-sook said on 2026-09-01 that she will stake her job on ensuring the government's housing supply plan goes as planned. ^[1] The authors emphasized that creating a structure where all citizens can enjoy a dignified life regardless of their region is the last solution to support the future of South Korea. ^[2] The authors stated in the introduction that the overpopulation in the capital region has reached a critical point in all fields including housing, transportation, environment, and welfare, and that South Korea cannot be sustainable with capital region growth alone. ^[3] The book 'Swamp of Imbalance: Rewriting the Balanced Development Strategy for the Era of Regional Decline' was published by the Citizen Policy Workshop, a research institute under the Busan Citizen's Participation Association. ^[4] President Lee Jae Myung asked Prime Minister Han Seong-sook to consider the housing supply plan as an economic stimulus policy and focus all efforts on it during a Cabinet meeting on 2026-09-01. ^[5] The South Korean government announced plans to supply more than 230,000 additional homes in the Seoul metropolitan area by accelerating development on public land, lifting greenbelt restrictions, and supporting private-sector projects. ^[6] The 592-page book is structured into four parts: the first examines the significance and necessity of balanced development and presents various indicators showing regional imbalance; the second analyzes the status and characteristics of national balanced development policies under successive governments; the third points out structural problems in budget allocation and related laws; and the fourth contains policy improvement plans for non-capital region residents. ^[7] Prime Minister Han Seong-sook stated that she has been visiting construction sites every week to check on progress. ^[8]
