Consider this quote:
I think there are some very important problems that don’t get worked on naturally, that is, the market does not drive the scientists, the communicators, the thinkers, the governments, to do the right things. And only by paying attention to these things, and having brilliant people who care and draw other people in can we make as much progress as we need to.
The fascinating thing about the quote is that it could be used word-for-word to justify research, entrepreneurship, and philanthropy (not to mention public service and policy). An interesting reminder of their interrelationship.
