The principle of non-sacrifice is a basic requirement of any just society since it recognises man's right to pursue all his chosen values.
The principle of non-sacrifice states that individuals should not be forced to sacrifice their interests or values for the benefit of others. Instead, they should trade or cooperate with others voluntarily for the mutual benefit of both parties.
Let us take an example from game theory. We can use two principles to interact between two people: trade and sacrifice. In the case of trade, both people benefit from it - meaning you have a non-zero-sum game. In the case of sacrifice, one person benefits, and one loses - meaning, you have a zero-sum game.
Multiply these interactions millions and billions of times: a society based on trade would be significantly richer, while a society based on sacrifice would stay the same as it started. If you factor in consumption (need to eat, for example), a society based on sacrifice would stagnate and shrink.
For the keen observer, sacrifice is the same as competition under these game mechanics. Both sacrifice and competition are zero-sum games in which one person benefits and one loses.
So for a society to be both just (moral) and prosperous (practical), it should follow the principle of non-sacrifice.
You really got me thinking now kiddo. Hmmm. Yes.
