Which part of the Constitution of India declares the ideal of Welfare State?

Question

Accepted Answer

A welfare state is a concept of government where the state plays a key role in the protection and promotion of the economic and social well-being of its citizens. It is based on the principles of equality of opportunity, equitable distribution of wealth, and public responsibility for those unable to avail themselves of the minimal provisions for a good life.The Directive Principles of State Policy embody the concept of a welfare state. A fundamental feature of the welfare state is social insurance, a provision common to most advanced industrialized countries (National Social Assistance Programme).The welfare state also usually includes public provision of basic education, health services, and housing, etc. Under this system, the welfare of its citizens is the responsibility of the state. India is a welfare state. The fact that the Preamble of the Constitution itself envisages India to be a socialist state bears enough evidence for this.Source: Laxmikanth: Indian Polity
