let me ask you this. Have you ever given to a charity? Maybe to the victims of Katrina for instance, or the Tsunami in south west asia?

If so, you have a social conscience, if not, your argument might work.

If you have a social conscience, it means you care about what happens to others in your society and see value in helping those who for whatever reason are not as well off as yourself. As to who should pay more tax etc, that's a difficult one. Probably another topic entirely.
