It's more difficult, you know, to bring about positive change than it is to make money. It's much easier to make money, because it's a much easier way to measure success - the bottom line. When it comes to social consequences, they've got all different people acting in different ways, very difficult to even have a proper criterion of success. So, it's a difficult task. Why not use an entrepreneurial, rather than a bureaucratic, approach. As long as people genuinely care for the people they're trying to help, they can actually do a lot of good.
