neuro

According to recent neurophysiology there are four major brain circuits that provide your sense of well being.

The first circuit develops positive feelings.
The second circuit ameliorates negative feelings. Oddly, these two circuits are independent so you can be great at feeling good and also at feeling miserable. Manic depressives come to mind.
The third circuit is for mental focus.
The fourth circuit is for generosity.

Imagine that. An entire mental circuit - one out of only four - for generosity. In our capitalistic society money has replaced direct generosity, though. And in Ayn Randian Republicans, generosity has shrunk to a withered stump. Missing one out of the four well-being circuits might explain why they're so angry, miserable, and filled with hate for the different.

The generosity circuit makes evolutionary sense. Humans prosper in groups. A group where people help each other will succeed more than a group where they screw each other. Unfortunately, under the influence of Randian Republicanism, we are more and more becoming the second type of dog-eat-dog society, which is the real reason America is going down the drain. And as the one percent impoverishes us we will tear at each other more and more for the few scraps they leave.
