David Henderson has already blogged about the Gary Becker interview in today's WSJ, so there is not point in trying to say much the same. Becker is old enough and accomplished enough to merit being seriously referred to as "wise". This is why I find his optimism so attractive.
Day-to-day, there is plenty to fret about and there is enough ugliness in the world for serious worry. But the long view is not so bad. Who better to take the long view than someone who we can seriously accept as being wise?
