There are a number of quotes that could summarize the motto for comtemporary culture in Fahrenheit 451, but all relate to the anesthetizing of the people and the destruction of knowledge in the interest of "equality."
The best motto may be Beatty's comment:
We must all be alike. Not everyone born free and equal as the Constitution says, but everyone MADE free. Each man the image of every other; then all are happy....
Still relevant in 2009, isn't it?
