One of my favorite Martin Luther King, Jr. quotes is:
"A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death."
My all-time favorite is:
"We have guided missiles and misguided men"
Both of these quotes make you realize that there is something structurally wrong with the way we have organized our society. We give up too much happiness to inflict too much pain, and that is a fool's bargain.
