What percentage of the U.S. is wealthy?

By whom?

"Rich" is a relative term. Even those people in the US that are at the official federal "poverty level" might be considered rich by the standards of someone in a third-world country. There's a glurge-tastic passage that's sometimes read by church leaders that asks questions about if you had a drink of clean water today, or a roof over your head last night, or how many of your children have died of starvation (and on and on and on) and then explains that "you're rich."
