All nations of people attempt to set up a system they regard as "just" and proper. There's nothing unusual about that. They enshrine their ideas about what is just and proper in their laws and their official documents.

When it comes to putting those ideas into practice, however, a number of things can go wrong and often do.

Furthermore, those ideas may make sense to one group of people, but not to another. The laws of a country usually turn out in practice to be more beneficial to the rich and powerful than they are to the poor and powerless.
