  The nature of the dispute between the right-wing and left-wing Lockeans emerges into view when we consider justice across generations. Suppose at one time the Earth is unowned and persons alive then appropriate all valuable land. On the next day, new people are born. What natural rights to land do they have? The left-libertarian holds that the doctrine of ownership must provide for fair treatment of each successive generation, and this requires that each new person has a right to an equal share of the value of unimproved resources or to some similar entitlement. The right-libertarian holds that the Lockean Proviso fully accommodates the legitimate claims of new persons. On this view, there is no fundamental right to an equal share in any sense. Luck plays a legitimate role in the operation of a natural rights regime. Granted, it is bad luck for me if I am born uncharming and lacking in good lucks and others are not voluntarily willing to enter into romance or friendship with me, but my distressed condition does not tend to show that my rights have been violated. And granted, it is bad luck for me if I come late on the scene and those who came first happen to be far better off in material wealth prospects than I, but the fact that there are unequal prospects does not tend to show that my rights have been violated. Provided the Lockean proviso is continuously satisfied and the appropriations by others leave me no worse off than I would have been under continued free use, my being worse off than others gives me no moral complaint against their property holdings.
