People who have come through a bad situation where they have almost died are often happy with drab. For a while. Drab is a relief if you've been fighting for your life for a while. But it doesn't last. The human mind craves entertainment above all else. Entertainment and contrast. You'd be surprised how much entertainment is nothing but contrast. Very few people can be happy with drab for any length of time. That's why utopias never work; that's why real communism flops every time. Conflict, challenge, contrast. We'll kill for it---and do so daily.
I am the world's leading proponent of true high quality entertainment. The higher quality, more stimulating entertainment you have, the less need there is to go out and murder someone to amuse yourself.
