Not likely. The 60’s had riots, Vietnam, political assassinations, Cuban missile crisis and ongoing Cold War MAD fears. The 1910-1940’s were jam packed with world wars, the Great Depression, Spanish flu, and more. And before that a quarter of all children died young. Every generation ever. What’s actually unprecedented is having a few years between crises where things are actually pretty ok!
Shhhhh, you're harshing the millennial vibe. Remember that due to their constant suffering the millennials are the most empathetic generation ever and everyone else are the narcissists.
