Imo this excerpt from Rothbard's Markets and Power provides the best demolition of the whole ridiculous idea of equality.
TL;DR: "Human life is not some sort of race or game in which each person should start from an identical mark. It is an attempt by each man to be as happy as possible. And each person could not begin from the same point, for the world has not just come into being; it is diverse and infinitely varied in its parts. "
Full text which is amazing:
"the diversity of mankind is a basic postulate of our knowledge of human beings. But if mankind is diverse and individuated, then how can anyone propose equality as an ideal? Every year, scholars hold Conferences on Equality and call for greater equality, and no one challenges the basic tenet. But what justification can equality find in the nature of man? If each individual is unique, how else can he be made "equal" to others than by destroying most of what is human in him and reducing human society to the mindless uniformity of the ant heap? It is the task of the egalitarian, who confidently enters the scene to inform the economist of his ultimate ethical goal, to prove his case. He must show how equality can be compatible with the nature of mankind and must defend the feasibility of a possible egalitarian world.
But the egalitarian is in even direr straits, for it can be shown that equality of income is an impossible goal for mankind. Income can never be equal. Income must be considered, of course, in real and not in money terms; otherwise there would be no true equality. Yet real income can never be equalized. For how can a New Yorker's enjoyment of the Manhattan skyline be equalized with an Indian's? How can the New Yorker swim in the Ganges as well as an Indian? Since every individual is necessarily situated in a different space, every individual's real income must differ from good to good and from person to person. There is no way to combine goods of different types, to measure some income "level," so it is meaningless to try to arrive at some sort of "equal" level. The fact must be faced that equality cannot be achieved because it is a conceptually impossible goal for man, by virtue of his necessary dispersion in location and diversity among individuals. But if equality is an absurd (and therefore irrational) goal, then any effort to approach equality is correspondingly absurd. If a goal is pointless, then any attempt to attain it is similarly pointless.
Many people believe that, though equality of income is an absurd ideal, it can be replaced by the ideal of equality of opportunity. Yet this, too, is as meaningless as the former concept. How can the New Yorker's opportunity and the Indian's opportunity to sail around Manhattan, or to swim in the Ganges, be "equalized"? Man's inevitable diversity of location effectively eliminates any possibility of equalizing "opportunity."…
Human life is not some sort of race or game in which each person should start from an identical mark. It is an attempt by each man to be as happy as possible. And each person could not begin from the same point, for the world has not just come into being; it is diverse and infinitely varied in its parts. The mere fact that one individual is necessarily born in a different place from someone else immediately insures that his inherited opportunity cannot be the same as his neighbor's. The drive for equality of opportunity would also require the abolition of the family since different parents have unequal abilities; it would require the communal rearing of children. The State would have to nationalize all babies and raise them in State nurseries under "equal" conditions. But even here conditions cannot be the same, because different State officials will themselves have different abilities and personalities. And equality can never be achieved because of necessary differences of location."
