The concept of Fairness

The concept of fairness is difficult for me to let go. The idea is of course a construct of humans. It sprang from our desire to make some sense of the world around us. Likewise, I think religion came from the same place, and perhaps it is the source of the concept of what is fair.
The universal forces act as they act, regardless of human feelings or concepts. So if we cannot expect fair treatment from the extraneous world then at least we *should* be able to expect it from other like minded people. That is if only they can see past their personal need, want, feeling of justification, greed, etc.
So where are these like minded people? They fade in and out.
They all can seem to find justifications as to why they deserve better and therefore do not have to be fair. I do not wish to be hypocritical and point all fingers outward; I too am guilty, more often than I'd like to be, of such thoughts and actions. I try to recognize it in myself and take the opportunity to change or rethink my action.
Do not think that philosophy or religion are the answers. They may be used as tools to gain the personal strength of character necessary to grasp and promote fairness. Philosophy and religion can help teach the concepts to people unexposed by their particular upbringing. But to make fairness a part of your daily thoughts and actions takes personal practice and fortitude.
Fairness and other 'humanely' concepts, like compassion and kindness, are worth the effort otherwise we're reptiles.
And I for one am tired of sharing my world with human reptiles.
