Plunder has been part of society for generations and it has not gone away. Both seen as necessary yet frowned upon. The concept of plunder can be applied almost universally across the different aspect of life.
Building to get ahead and capitalise on loss is a form of plunder but the moral values of taking what did not belong to someone is the other side of the issue.
Plunder might have started as a desire but it is now a necessity needed to survive as the race to attain certain forms of value is inevitable.
