E/C.12/HND/CO/2 comparative studies on equal pay for work of equal value among all organizations and professions, with a view to formulating a comprehensive strategy in this regard. Social security 35. The Committee welcomes the reforms under way in the social security system pursuant to the Framework Act on the Social Protection System. It is concerned, however, that the social security system still does not cover a significant portion of the population and that the State party does not yet have a universal social protection system that provides minimum essential coverage to the entire population (art. 9). 36. Bearing in mind its general comment No. 19 (2008) on the right to social security and its 2015 statement on social protection floors, the Committee urges the State party to: (a) Ensure that the Framework Act on the Social Protection System provides a system of social security that guarantees universal social coverage and ensures appropriate benefits for all workers and non-contributory benefits for individuals and families from the most disadvantaged and marginalized groups, so that they may enjoy an adequate standard of living; (b) Redouble its efforts to set social protection floors that guarantee access to basic services; (c) Take the necessary steps to ensure that the social security system operates effectively, including when the responsibility for guaranteeing the enjoyment of this right, in particular with regard to the pension system, has been delegated to non-State entities. Children and adolescents in situations of vulnerability 37. The Committee notes with concern the information received about the vulnerable situation in which many children and adolescents live in the State party, in particular children who live in the street. The Committee regrets that the State party did not provide statistical data on the extent of the problem of street children. The Committee is also concerned by the risk that many children face of being recruited by gangs to commit crimes and by the magnitude of the problem of child labour, especially in the case of children engaged in hazardous work (art. 10). 38. The Committee recommends that the State party: (a) Establish a system to provide comprehensive protection for children and adolescents, in particular those living in special situations of vulnerability, such as children who live in the street; (b) Conduct a thorough study on the extent of the problem of street children in order to take a comprehensive approach to addressing the problem; (c) Adopt effective measures to protect children and adolescents who are victims of violence and prevent them from being recruited by gangs and used to commit crimes; (d) Adopt effective measures to prevent and counter the economic exploitation of children by ensuring that child labour legislation is rigorously enforced, strengthening child labour inspection mechanisms and providing support to poor families to make sure that their children attend school; (e) Ensure that all instances of economic or any other type of exploitation of children are thoroughly investigated and that those responsible are duly punished. 8 GE.16-11828
