This Memorial Day weekend, did you spend more time thinking about what kind of beer and brats you'd buy for your picnic than about the 1.2 million who have given their lives in uniform? Did the latter even cross your mind?
Yes, the President will be speaking platitudes (truthful) today about the courage and tragedy of those who lost their lives. But, I would wager that most people, while aware that Memorial Day is a federal holiday to commemorate our military dead, are indifferent to the gravitas of this holiday. Setting aside your position on the propriety of more recent armed conflicts (Iraq, Afghanistan, Vietnam), one thing you know for certain: many persons, typically young and working-class, have given their life wearing a U.S. uniform.
How to account then for the fact that this very serious holiday has become little more than the official start of summer? There are several forces at work, and I will try to parse them out.
Americans are Uncomfortable with Mortality
For a country remarkably comfortable with violent movie content and a high murder rate, we are uncomfortable with mortality. If we can avoid it, we do. Thus the proliferation of every possible treatment or surgery on the body to avoid signs of aging. If we are 60, we want to look 40. Memorial Day is a day to deal with the fact that our nation has lost 1.2 million soldiers and sailors acting at our direction (yes, we're a democracy). Since we're uncomfortable with this reality, and our own mortality, we have transitioned Memorial Day into a vapid summer launch celebration.
Americans Don't Like Downers
In a similar vein as the previous example, American are relentlessly optimistic and avoid undue analysis of their actions. We are not a moody people and don't like to dwell on the past, much less a bloody past (except when we re-enact Civil War battles - which we'll then ignore on Memorial Day). It probably would've made sense to have memorial periods after major conflicts and wars (like a 10-year period), give the dead their due and then "bury" that particular war in a proper way. Of course, we would not then have a 3-day weekend for decades. In a strange way, this is a strength - we can avoid replaying bloody history (as in Ireland, Rwanda etc...) by simply forgetting it.
