How should South Asians think about charity?

There was an article written on the Freakonomics website several days ago about how South Asians should approch charity.

The article is here.

This got me thinking about the topic which is related to an earlier post on this blog about giving back to society. The article I mention above is about how South Asians are more well-to-do than average Americans but still have not found their voice when it comes to philanthropy and mobilized themselves to have more voice in society and government.

I find this to be one of the critical challenges for South Asians over the next 25 yrs. We are a group of people in the US who are highly educated and have more wealth than most Americans, yet we have not found a way to mobilize ourselves and speak w one voice.

Will we ever get there? How can we do this? Should we try to do this?
