Riots may ensue as more poor Americans recognize their "miserable" long-term prospects.
- How bad is wealth inequality in the United States? About 1 percent of Americans hold 80 percent of the money.
- In the United States, the correlation between the income of parents and the income of their children when they grow up is higher than in any other country in the world.

In 1968, 19-year-old Paul Robert Cohen was arrested for disturbing the peace by wearing a jacked that read "F*ck the Draft" in a California courthouse. His case went to the U.S. Supreme Court, which decided that being offended by the jacket did not merit censorship.
- Jonathan Zimmerman argues that the history of debate in the U.S. – of who gets to say what, and how that has evolved – should be taught to every American.
- Zimmerman also says it's ahistorical for free speech to be cast as a conservative issue. For much of U.S. history, champions of free speech were those who fought for social justice to help the powerless keep the only power they had: their voices.
