I was reading the Progress Principle today. It makes the point that setbacks have an outsized influence on one's mental makeup - much more than progress does. Check it out.
What corruption leads to is a set of daily setbacks to individuals. On the one hand the govt says this problem is impossible to solve. On the other the protestors say they have researched the issue and here is a way to solve it.
Which one do you pick and support ? It's a no contest to me.
I may have been ambivalent in April. But now in Aug, seeing that the govt has watered down their version of the bill so much that their lokpal won't even accept allegations of corruption from the general public ... it is clear they have a vested interest in maintaining the status quo. That made me more interested in the topic and I read the bill and both sides of the argument. My conclusion is that this is the chance to grab. Even if it reduces corruption by a few percentage points it will be a victory, and will release energy for the tasks that you mention so urgently need to get done.
