I thnik that the invention of money was the worst of them all... It made people think that painted paper is more important than the planet we live in. Nobody cares that they are going to die in 5 years from destroying our natural system, our forests, because they are paying a lot for the job. What is money useful for when the world ends? When our society collapses? Money is just paper. The same you smash and throw in the garbage just because you did a bad drawing.
