You acknowledge that part of the above is in error in a subsequent post. I wanted to comment on the second sentence in the quotation. Its content seems to imply the notion that we can feel a sense of injustice from our observing the injustices of others. This seems like a very Humean position with regard to the origin of a possibility of altruism (phrase stolen from Tom Nagel's 1978 book of the same title). I'd like to understand the connection between the two forms of injustice as you see it, if any exists.

Those of us whose value system is based on individual achievement find this abhorrent. An example nepotism has been the standard for centuries, now it is considered passe.
The force of these two quotations seems to push one towards acceptance of ethical relativism. Needs may well be relative; so may be the means by which oneseeks to instantiate one's values. However, I am unwilling to accept relativism of values themselves. To do so is to undercut the claim that we can be altruistic and concede the field to the Ayn Rands of the world.
