Greed drives thoughts and can be seen around by the numerous start-ups that take wings around us. I move in circles where the marriage of finance and technology is bringing out amazing ideas. Okay, some of it is amazing to the extent of being absurd. For instance, I heard a young chartered accountant go gaga about how his venture would make tax filing a five minute exercise and scale up to have 100 million users over three years. I had no intention of killing his enthusiasm, considering the fact that data shared by the tax authorities indicate that we had 2.87 crore individuals who filed income tax returns in 2012-13.
