Great Album, but it's partly a musical interpretation of Animal Farm by George Orwell, which was published in 1945. Which, as stated on Wikipedia, is based on events of the Spanish Civil war 1936, and the 1917 Russian revolution. So anywhere from ~89 to ~116 years ago. There's also The Lord of the Flies published 1954 which has a similar theme . So what is the statement?
I was optimistic during the 1960's and 70's (which were much harder then today to be optimistic) and I still am. My father lived through the 1930's and 1940's, which were even harder to be optimistic. Better to be optimistic then to live being scared all the time of change and the future. You cannot stop either, although some people have always tried to stop it (I am referring to the Industrial Revolution mostly). The latest fear is AI. It's always something. Can't live your life that way. That's not living, it's basically slowly dying.
Only thing that got me depressed lately was when John Prine died for no good reason. Luckily we still have his music. Apologies if this isn't hilarious.
