"America touts itself as the land of the free, but the number one freedom that you and I have is the freedom to enter into a subservient role in the workplace. Once you exercise this freedom you've lost all control over what you do, what is produced, and how it is produced. And in the end, the product doesn't belong to you. The only way you can avoid bosses and jobs is if you don't care about making a living. Which leads to the second freedom: the freedom to starve." - Tom Morello
