Much has been made of the shifting cultural sands of the planet. Many people have an opinion on the subject. Mark Steyn has an article which also encapsulates many of my own thoughts.
Everything can be boiled down to evolution. As I and Citizen Prime (the spouse) were watching her favorite show (Travel Channel's Most Haunted), I remarked how men's earrings were no longer worthy of mention. At one point they were a defining statement for sexuality, criminal alignment or a host of other subcultural identifiers. Now they are simply there. Most are worn by the young and trendy (not my demographic). But in the space of less than two decades, their presence has become de riguer.
I contend that the present trend in population also will predict the future state of the world. A former boss of mine, CAPT Tim Scheib (USN), stated that the way to shape a culture is simple. Control the press, control the police and control the schools.
But by far the best impact is the schools.
