Societies just move ahead without a direction. They do not seem to know where they are headed. Even if they did, I am sure, what societies do may not take them to where they want to be. Although actions of societies are catalysts, its hard to predict the direction! All I want to convey is, it is less worth !(though not worthless) to try to do right things beliving they would contribute to a better society.
While we contribute to a chaos we can hope that order will emerge. Hope does not cost anything :)
Now that you have a reson to err , do not go ransacking the world. I am still living in it :)
