If you look across the Political spectrum in the USA you will find it being run by psychopaths. This is also true in other Western Countries. The closer their economies modeled on Laissez-faire Capitalism and that thing they call “The Free Market” , the greater the preponderance of those sociopaths and psychopaths in the halls of power.
This because that system DIRECTLY rewards that type of behaviour. The less empathy for others , the more wealth and power that is garnered. The greater the focus on wealth and power, the less empathy for others. The system just reinforces itself to the point where it devolves into a “Your Fired” Donald S Trump “Reality Star” in power.
There an interesting observation made by an author in a book I once read some time ago (and I wish I could remember its name) and that was of the first interactions between Europeans and the First nations peoples they encountered. This was in regards to how the entering into treaties was seen by both sides. The Author ackowledged that the various tribes warred on one another but after such wars became too great a stress on a society would sit down with one another to arrive at some sort of peace. The difference in their model was that in order to arrive at that peace BOTH sides had to see a benefit and both sides should be able to prosper after the peace. The European model of peace treaties was one side deemed the “winner” and the other side deemed the “loser” and the “Winner” would dictate all terms. The First Nations tribes felt that this lead to enimity and would only perpetuate conflict and that it would not encourage a harmonious relationship between the groups.
Capitalism is part of this “winner and loser Model” which fuels Militarism and conflict. This is one reason the USA has been at war for 90 percent of its history and puts forth as leaders peoples like Bolton.
