Last week, Mark Perry at Carpe Diem put up this post with a video. The point was that globalization, capitalism (and trade) helped save the Chilean miners. I'm not one to say they were doomed without the forces of economics. But economic forces certainly helped. And it was capitalism in the best way - the way that Adam Smith intended when he wrote both The Theory of Moral Sentiments and An Inquiry into the Nature and Causes of the Wealth of Nations.
But, it was a profit motive that developed the technology. And it was also the idea that we best serve ourselves by serving others that led many firms in many nations to make the technology available. The idea was brought home, yet again over the weekend when this article appeared in my local newspaper, The Richmond Times-Dispatch.
It's just something to think about and discuss with your students. As always, I welcome your comments.
