Interesting answer. I feel that even if we don't assign values, society has inherent values on people (Poor people get less healthcare, higher tax rates, bills, go in ripped clothes to a restoraunt, and see what happens).

I personaly try to talk to friends equaly if possible, but I would move out of the way for a veteran right away, and tend to treat other people as being more worth than me.

I feel that they have a "something" that makes them more of a person.

I also have a higher respect for Doctors/Engineers/scientists and really like those (but not sure that counts as seeing them as "worth" more per-se).

There's also the moral dimension. See what happens to cheaters for example. Not that I condone that, I just think people should avoid them for closed relationships.
