I'm not sure "everyone" "should" read any book, but for wide appeal, with great messages and or stories, how about:
To Kill a Mockingbird -- we all surely agree
The Phantom Tollbooth -- thought provoking word and idea juxtapositions
Searching for Signs of Intelligent Life in the Universe -- poignant, "real" (though some may think dated, but the overall messages are timeless) and again, the perspectives.

Hey, that Popular Mechanics is a neat answer.
FYI:, as far as periodicals, "Wired" keeps you up to date and it's incredible what's happening. Also well-written.

One more thing: USA Today print version is very readable, user friendly way to learn to "take the pulse of" and become quickly familiar with topics from the Syrian rebellion to a local state and city's happenings.
