Seoul led with 231 minor-owned businesses, followed by Gyeonggi Province with 61, and Incheon with 22.
Jin Sun-mee, a member of the National Assembly, has called for stricter regulations to curb the use of minors in business ownership as a tactic to avoid inheritance taxes, emphasizing the need for greater oversight to address the broader issue of income inequality.
