At the one extreme, social service provision by government may be seen as the work of benevolent professionals, and at the other as that of tyrannical social engineers. This paper examines the views of the libertarian economist, F.A. Hayek, and the British sociologist and philosopher, T.H. Marshall, on such provision. Marshall takes an optimistic view of the development of the professional classes in Britain and elsewhere; he sees social welfare specialists as essential to the preservation of social rights and argues (...) they should be given powers that sometimes supersede democratic preferences. Hayek, however, sees these professionals, in their drive to promote social equality, as a danger to liberty in Western democracies; he thus opposes a democratic system in which such people are allowed to attain influence. Both Hayek and Marshall raise questions about welfare and inequality and about the degree of authority social welfare professionals should be given. However, they take opposing views on the proper role of what Burke called ?natural aristocracy? (shrink)
