Gibson says in places like India, which he has written a lot about, he's seen unbounded optimism in business circles: "India has a can-do spirit ... India has a lot of problems ... 40% of the world's poor, dreadful pollution ... but India says 'let's turn that problem into an opportunity' ... and there are very good examples there of social innovation."

He cites the Grameen Bank, which gives micro credit to the poor; and the Tata Nano, the world's cheapest car, costing a mere $2,500 -- as examples of India's social innovation.
