They don't mention that so few people have served in the military these days. Wearing hats could have easily been more popular because so many more men were veterans back in the days after WWI and WWII. They would have been used to wearing hats after being in the service. The time hats started dropping off in popularity also correlates with the rise of the anti-war movement brought on by the Vietnam war. Also in the 1960s the Catholic Church stopped requiring women to wear hats in church.
