There is certainly reason to be concerned about things like future inflation, government deficits, and high unemployment. However, I don't think the doomsday scenario is the likely outcome. I will refer you to one more book, Sonic Boom, which does an excellent job of discussing the complexity of today's world in which the rapid pace of change makes us all a bit uncomfortable. We live in a truly globalized world, and, like it or not, we are all in it together. I believe that unpredictable changes will shape our future and that, for the most part, these changes will be to our benefit in the long run.
I hope everyone has a very Merry Christmas and Happy New Year!
