A welfare state can be defined as a model of government in which the state plays a pivotal role in both the protection and the promotion of the social and the economic well-being of its residents or dwellers. It is usually based on the principles of equal opportunity for all men and women alike regardless of their gender, race or ethnicity along with an unbiased and equal distribution of wealth as well as public responsibility of especially those citizens who are unable to avail even the minimal provisions of a good life by themselves. (Phillip Anthony O'Hara,1999)
