[quote]The Vietnam War tore society apart
A lot of individual events have torn American society apart over the years: the Civil War, Prohibition, the Vietnam War, McCarthyism, Lincoln and Kennedy assassinations, MLK assassination, 9/11, the world wars, the so-called Indian Wars, 1929 stock market crash and following Depression, Watergate, the Bonus Army being attacked.
Then there were the smaller but still traumatic individual events: Kent State, Iran hostages, Galveston hurricane, SF fire, Dred Scott, Kansas-Nebraska Act, Teapot Dome, the Dust Bowl, the Cold War and nuclear fears, Lusitania, Challenger.
Then there are the long-term problems and sociocultural movements that have caused long-standing conflicts: gay rights, abortion, women's suffrage, civil rights, Cold War, gun violence and school shootings, veteran's rights, education.
There's more, but the bottom line is that the country goes through individual traumas every few years, all while navigating long-term problems like racism and loss of (and definition of) rights. At the same time, a government more concerned with big business and capitalism than the individual citizen, all sorts of attacks from foreign countries, a cohesive movement to reduce (if not eliminate) education for most people, loss of a free and nonpartisan press, and the usual conflicts between the secular and the religious have made these traumas impossible to deal with on a nationwide level.
A nation can only handle so much before it collapses under the weight of all this. For generations, all we've done is whitewash the facts, put a bandage on problems, and then try to forget they ever happened. That's why you don't know about the Bonus Army. That's why we elected a corrupt Republican as president just six years after the last corrupt Republican had to resign because of his crimes. That's why people think the only real problem facing us is fat people who eat too much high fructose corn syrup.
