Also, after a few decades without war, a capitalistic society tends to become more prosperous, and social pressure increase. The constant elevation of material wealth as the goal of all worthy citizens increases competition. Inevitably, the bully mentality is the most successful common-denominator tactic in a competitive environment. So, over time, a purely capitalistic system produces a population of greedy bullies in leadership roles.
The whole idea of war gradually becomes more attractive and supported by a competitive society. Then, wars commence.
In other words, in a capitalistic system, there are at least two elements that favor war: the primacy and insatiability of greed, and the tendency of humans to quickly forget pain.
the tendency of humans to quickly forget pain.
I don't think people forget pain, as a matter of fact I think that anyone who experiences a war or other catastrophe directly never fully recovers.
What happens is that a new generation arises that has never been involved in wanton destruction and so is easily manipulated to support or participate in the next cycle. Notice that those who started the current wars have no members who actually were involved in the previous ones. Policies not Politics ---- Daily Landscape
