From a purely phyiscal human standpoint, life is cheap and futile. Because of our insecurities, we are prone to worry about our personal woes and then collectively amplify that to a global scale. But the history of the world as we know it shows a pattern of survival and adaptation.
I recently had a conversation with a JW about the state of world, sparked by that favorite subject about "how bad things are getting." I asked him what was actually so bad. He mentioned immorality and violence in entertainment, comparing our day with the 1950-60s when he was a kid. It struck me that he had proved the degradation of society by comparing events in his lifetime only. Most JWs do this.
But if you zoom out and look at the last 3,000 years of history you will see as socially acceptable: Slavery, live violence as sport, women treated as property, dictatorial control over mind and body, ethnic cleansing.
Of course all of the above is still present today. But the majority of the world do not consider them acceptable.
If you ask me what period of time I would like to live in if I had the choice, it would be now. Come what may, we live in a world of knowledge and free thought. The living standard, on average, is higher then ever before. We are the most enabled people of all time. Just the fact that I can type these words and know they will be published worldwide, in an instant, is incredible.
What I just wrote will go out the window the next time a major catastrophe happens, man-made or natural. The lost will go in droves to JWs and every other cult that offers all the answers. But that doesn't change the fact that, collectively, this is a great time to be alive.
