Matthew E. Kahn – Arthur Brooks’ OP-ED focuses on the politics of optimism but I would prefer to recast his focus on what should be the basis of our optimism about our collective future.  In 2015, we live in a world with roughly 7.3 billion people whose life expectancy is higher than it has every been.  Educational attainment is higher than it has ever been. Urbanization both insulates us from climate shocks and facilitates trade and learning. Anticipating a longer life time and lower infant mortality, families are having fewer children and investing more in the human capital of each child. These children (through the dynamic complementarity mechanism of learning begets learning) are more likely than previous cohorts to achieve their full potential.  While many progressives yearn for a return to 1950s America, I have argued (see this post and this post) that those days were not as great as they recall and the rest of the world was not in terrific shape then (think of China).
