Mcdonalds cheeseburgers. I saw a video of a guy doing the pacific trail with just a bag of hamburgers and he said they lasted well over a month. He also said its the best thing hes ever done as they gave him more strength than protein bars ever have. If i find it ill post.
Edit:I couldnt find the hamburger but i found mcdouble guy. I think 90 miles is still a few days worth.
My ideal world is always communism where everyone has a role and those roles only export is prosperity and happiness. Something like the Rajneesh movement. It is deeply flawed and will never work globally but its a nice thought.
If you would have asked people 100 years ago they would be saying what we are living in today is the utopia. So this is always going to be a moving goalpost.
