I think that this universe is based on laws or rules which favor balance. Lightening is the discharge of static electricity into the atmosphere or into the ground which brings a balance between the two (cloud to cloud, internal inside a cloud, ground to sky and sky to ground). Doesn't matter. It brings an electrical balance back into existence.
There are countless examples in physics, chemistry, and bio-chemistry - our body's reaction to any number of foreign substances is simply our body's mechanism(s) for returning our systems back into balance. And as this logic would suggest - when something throws our body (or the environment, etc...) so far out of balance that they system cannot correct for it - the system fails... our bodies fail... the environment dies...
In human behavior. I also feel that some sort of balance between individual goals and the betterment of society have to be reached to enable progress.
If there is no personal motivation or subsequent reward for engaging in this or that behavior, then you'll find the drive to participate in the behavior deteriorates and we move on to other things.
At the same time you can't blindly or carelessly do whatever you want without concern for those around you because the accepted (general) construct of our society says that we must work together for our society to function.
You can look at our history, sociological - etc... to see why we formed communities - strength in numbers - sharing work loads, etc... Just as all other higher primates live in troupes or communities of some sort.
I think what trips us up is the notion of morality and the varying definitions of what is "moral" as you move from one group to another.
I know from my personal experience in Corporate America - bet you never figured you'd read someone quote Corp America experience as a great teacher of history in systems... LOL...
In sales systems where the sales people are expected to work off 100% commission; if your company wants to continually motivate these sales people and provide incentive for their "staying hungry", you'd never want to cap their potential commission rate.
Example - You sell "X" product and it costs "Y" amount, your commission is "Z".
If you sell "Q" product, which is far more difficult to sell and it costs "Y multiplied by 4", you'd expect a commission of "Z multiplied by 4". But a lot of companies set themselves up for disaster by saying - no. If you sell "Q", your commission is only "Z". T...
