Why Nothing Hapens
People possess a very remarkable power: they can act, in the many numbers that there are, to solve a problem. There are many severe, immediate, and very present problems, and people do react to them. They can reacte in very strange or dangerous ways, and cause much destruction, but they can also make things far better.
The effect diminishes with the failing force of the evil. The small problems that face the world are not met with the force of the whole human race. However, the appearance and existence of evil are very different things. Some of the worst of the worlds problems are simply too distant to be seen. Then there are those that are clouded by the very experiences of those who face them.
This would not be such a damaging effect if not for the very slow moving spirit of the human race. It is one very large entity, too large to adjust quickly. An individual may change quickly, but the whole of the human race is unmoving except but slowly. And so in the absence of a direct threat, people do not respond.
One possible solution to this would be to conjure up a direct threat and motive people to action. Another would be to draw upon people's sense of loyalty and patriotism. But such insentives can be horribly misdirected. They would more appropriately remain no more than part of the human race that is, and not the part that wills or does.
There is another hope, and that is in the tendency of people to immitate eachother. If people can be accostomed to acting at the persistent instead of the threatening problems, it may be possible, if not to change human nature, to change the context in which it lies.
