Let's take stock of young America. Compared to previous generations, American youth have more schooling (college enrollments have never been higher); more money ($100 a week in disposable income); more leisure time (five hours a day); and more news and information (Internet, The Daily Show, RSS feeds).What do they do with all that time and money? They download, upload, IM, post, chat, and network. (Nine of their top ten sites are for social networking.) They watch television and play video games (2 to 4 hours per day).And here is what they don't do: They don't read, even online (two thirds aren't proficient in reading); they don't follow politics (most can't name their mayor, governor, or senator); they don't maintain a brisk work ethic (just ask employers); and they don't vote regularly (45 percent can't comprehend a ballot).They are the dumbest generation. They enjoy all the advantages of a prosperous, high-tech society. Digital technology has fabulously empowered them, loosened the hold of elders. Yet adolescents use these tools to wrap themselves in a generational cocoon filled with puerile banter and coarse images. The founts of knowledge are everywhere, but the rising generation camps in the desert, exchanging stories, pictures, tunes, and texts, savoring the thrill of peer attention. If they don't change, they will be remembered as fortunate ones who were unworthy of the privileges they inherited. They may even be the generation that lost that great American heritage, forever.
