Scholars representing this school of left-libertarianism often understand their position in contrast to right-libertarians, who maintain that there are no fair share constraints on use or appropriation that individuals have the power to appropriate unowned things by claiming them (usually by mixing their labor with them) and deny any other conditions or considerations are relevant and that there is no justification for the state to redistribute resources to the needy or to overcome market failures. A number of left-libertarians of this school argue for the desirability of some state social welfare programs. Left-libertarians of the Carson–Long left-libertarianism school typically endorse the labor-based property rights that Steiner–Vallentyne left-libertarians reject, but they hold that implementing such rights would have radical rather than conservative consequences.
