Throughout the ages people have lived the path of least resistance.
Thus: doing what’s easiest.
As a species our approach is only to survive.
Whatever is the easiest way to survive is what we do.
Furthermore, whatever is in vogue is what is chased.
For instance, when the king and queen rule, we follow.
When a government disagrees with someone we go to war.
When the in thing is to have silver we mine and sell silver.
The same with gold and fur.
Whatever is sold in our shops is designed to make our lives easy.
