Essentially, as you see, there is much distress going on in our society today (and in the world). Many ask themselves what to do, many don't. Some think the solution is war. Many that it is pacifism. Many that it is free market, others socialism.
For those who ask this question, one easy thing to do is to help others. The more you help others, the more you produce a good effect on society. Psychologically, it has been proven that those who have been helped, are more likely to help others. Thus help creates a positive chain of effects (like Buddhism has been telling us since its beginning).
It doesn't matter what you believe when you help them. It may be God, or nothing. But helping others is a good thing to do, in any case. And something which you can do now.
