Business is based on the well-known principle of supply and demand. You want something, the other man has it. The only thing left to settle is the price.

Men don't want to be brothers - they may someday, but they don't now. My belief in the brotherhood of man died the day I arrived in London last week, when I observed the people standing in a Tube train resolutely refuse to move up and make room for those who entered. You won't turn people into angels by appealing to their better natures just yet awhile - but by judicious force you can coerce them into behaving more or less decently to one another to go on with. I will still believe in the brotherhood of man, but it's not coming yet awhile. Say another ten thousand years or so. It's no good being impatient. Evolution is a slow process.

Bad habit, lunch. A banana and a water biscuit is all any sane healthy man should need in the middle of the day.
