In his essay "From Liberty to Welfare", philosopher James P. Sterba argues that a morally consistent application of right-libertarian premises, including that of negative liberty, requires that a libertarian must endorse "the equality in the distribution of goods and resources required by a socialist state". Sterba presents the example of a typical conflict situation between the rich and poor "in order to see why libertarians are mistaken about what their ideal requires". He argues that such a situation is correctly seen as a conflict of negative liberties, saying that the right of the rich not to be interfered with in the satisfaction of their luxury needs is morally trumped by the right of the poor "not to be interfered with in taking from the surplus possessions of the rich what is necessary to satisfy their basic needs".
