A couple has four children. They are a typical family. The oldest loves vanilla ice cream, thus, naturally, the second likes chocolate, and the third likes something weird like bubblegum marshmallow. The last child hates ice cream altogether. They like chocolate chip cookies. The soft chewy kind.

While this frustrates the parents to no end, they don’t get upset because they know it is how it is; the children are not behaving immaturely, it is how we were designed,.. how we evolved. If the family is off on vacation and they stop at an ice cream shop it is more likely that at least one of the children will be happy. If all the children liked vanilla and the shop was out, then they would have four miserable children to contend with. This is how evolution ensures species survival.

With ice cream, this important concept is intentionally oversimplified. Nature does not care about us at all, and evolution does not care about us as individuals,.. only about our genes. And since all four children have the same genes, only one needs to survive and reproduce. More than one surviving is good, but not necessary.

In other words, nature is a roulette table, evolution is a gambler playing the odds, and the four children are the chips being wagered. It is better to spread the chips around the table than to put them all on one number. Over millions of years all life has evolved to instinctively spread the chips around the table. 

The significance of this, now, is that the world is composed mostly of people who are first born and second born children. Thus, there will never, ever be a universal consensus as to what should be done and how things should work. Any governing institution that does not embrace this reality and work to develop systems that respectfully allow people their differences will spend most of its time and energy putting out fires… until it succumbs and ceases to exist.
