A welfare state is a concept that states that the government plays a key role in protection and promotion of economic and social well-being of the citizens. A welfare state is based on the principle of equality and opportunity and equitable distribution of wealth. The concept of welfare state is mentioned in the Directive Principles of State Policy, which are mentioned in Part IV of the Constitution. The DPSPs are directions to the Central and State Governments in framing laws and policies. These provisions are not enforceable by any court of law but these are considered fundamental in providing for the welfare of the citizens by improving the social and economic conditions. These DPSPs mentions provisions such as 'adequate means of livelihood', 'fair distribution of material resources', 'just and humane conditions of work', which are necessary for the welfare of the people.
