What I find amazing is that large numbers of people continue to think that government - populated with as large a number of ninnies as anything on Earth - is what we should look to for solutions to the many problems we now face, most of which have been created by ... government. This is the grand stupidity of our age. And amazingly, it is the highly schooled who primarily subscribe to it.
