Is the issue that perhaps folks no longer have any conception of history because we are too bombarded with hyper-media and social media? My grandparents grew up on a farm in the great depression where it was common to have multiple siblings die of pneumonia, drowning or other maladies that are far less frequent. African Americans could not even vote until the 1960's in this country. For people to be so pessimistic today is fairly pathetic in my opinion. Humans have always evolved to adapt, work socially and creatively come up with solutions to huge problems from the last Ice age to the Nazis. People should move out of these horribly overpriced cities and get back to small, sustainable agriculture if they want to be happy. If you want a degree get one from a community college. Yeah we have huge problems to face today as many responders point out - specifically Climate Change, environmental destruction and income inequality. Remember in the 1940's we had to go face to face with the most evil empire the modern world has ever known along with our allies and most importantly Russia. I suggest folks toughen up a bit and know that things won't get any better without a steely resolve and working together.
