Equality, Value, and Merit by Friedrich A Hayek
The great aim of the struggle for liberty has been equality before the law. This equality under the rules which the state enforces may be supplemented by a similar equality of the rules that men voluntarily obey in their relations with one another. This extention of the principle of equality to the rules of moral and social conduct is the chief expression of what is commonly called the democratic spirit–and probably that aspect of it that does most to make inoffensive the inequalities that liberty necessarily produces.
Equality of the general rules of law and conduct, however, is the only kind of equality conducive to liberty and the only equality which we can secure without destroying liberty. Not only has liberty nothing to do with any other sort of equality, but it is even bound to produce inequality in many respects. This is the necessary result and part of the justification of individual liberty: if the result of individual liberty did not demonstrate that some manners of living are more successful than others, much of the case for it would vanish.
It is neither because it assumes that people are in fact equal nor because it attempts to make them equal that the argument for liberty demands that government treat them equally. This argument not only recognizes that individuals are very different but in a great measure rests on that assumption. It insists that these individual differences provide no justification for government to treat them differently. And it objects to the differences in treatment by the state that would be necessary if persons who are in fact very different were to be assured equal positions in life.
