Once upon a time:
The devil you knew was superstition, the devil you didn't was reason.
The devil you knew was conjecture, the devil you didn't was knowledge.
The devil you knew was trepidation, the devil you didn't was discovery.
The devil you knew was tyranny, the devil you didn't was democracy.
The devil you knew was slavery, the devil you didn't was freedom.
The devil you knew was a woman in her place, the devil you didn't was a woman fulfilling her potential.
The devil you knew was segregation, the devil you didn't was inclusion.
The devil you knew was uniformity, the devil you didn't was diversity.
The devil you knew was prejudice, the devil you didn't was understanding.

The devil you know is nearly 6 billion people living on less than $10 per day, 3 billion on less than $2.50 and 1.3 billion on less than $1.25.
