Since the campaigning was not oriented toward issues, the great families were able to maintain their superiority over the centuries by their inherited resources: their famous names, their wealth, and their clienteles of voters.
As we noted above, it is difficult in practice to divide inherited resources up literally in this way.
But a distinction can be made between the contribution that the inherited resources putatively credited to Roger make to production, and Roger's own contribution.
If Roger were not on the island we imagined, the other islanders could still use the inherited resources that we have supposed are otherwise credited to him.
It might be said that people like Roger do contribute to production by supplying their share of inherited resources for others to use for productive purposes.
In particular, DST uses the so-called parity argument to reject the view that DNA is uniquely informational while other inherited resources merely provide material support for reading or interpreting DNA (Griffiths & Knight 1998).
Therefore, it is suggested that measures should be given priority to preserve the authenticity of inherited resources, to improve the provision of supporting facilities, to promote coordination between different villages and village clusters, and to arrange people-oriented tourism routes.
It may be a concern of this kind that has lead some philosophers sympathetic to left-libertarianism to explore ways in which we might extend the scope of the left-libertarian argument beyond what we conventionally think of as inherited resources to cover other kinds of assets.
Up to this point, Dworkin's theory is strikingly similar to that of the left-libertarians we discussed above: he is, in effect, asserting the right of each person to an equal, marketable share of society's stock of inherited resources.
But, according to the left-libertarian, this is no different to Roger deciding to do no work and to live off the rent he can get from charging others to work on his machine: it is a legitimate use of one's rightful share of society's inherited resources.
