As a species they had just about everything going for them.
Their world had plenty of land for farming, the potential for an equal sharing of food was open to them, and there was enough wealth to go around for all. On the face of it, it was idyllic. There was so much that was plentiful, an abundance of everything. There was no need for anyone to worry about anything. However, ‘what could have been’ and ‘what was’, were two completely different things. The former did not allow for the all-pervasive push for more. More land, a great deal about land, more food, and more money. A never-ending striving for a bigger house, a nicer car, more expensive clothes, luxury travel, better quality food, and a better and more prestigious job. The people simply want more. There is no end to it.
Their masters, those who have all of these things and more, find that this endless craving quite naturally brings about a condition that is much to their liking.
This world is not far from home.
