Why does money affect our judgment so severely?

The answer is simple of course:

Money represents human effort. The less of which I have to expend, the more beneficial it is for me.

Getting human effort from another human being is a non-trivial task, and requires an organization, a purpose, a motivation.

Reducing it to cash, a few dollar bills or other forms of paper hides this facet of money, and makes it easier to think about it in terms that are not always clean. And yet, intuitively, it is always with us and couched in phrases like "Money makes the world go around"...

If we found a way to make the human effort behind money somehow explicit - then terms like billions of dollars and trillions of dollar would once again be awe-inspiring, and perhaps stop us before we do something unethical around it.
