The meek shall inherit the earth, but they won't get the best parking spots or airline upgrades. While the meek are often well liked because they're too cowardly to speak their minds, they're not often respected, like the little brother who never really grew big enough to exact revenge.
Being meek is fine if you're unattractive or suffering from post traumatic stress disorder, but not smart if you want free stuff or don't believe in the afterlife.
