CHICAGO — Melissa Greenwood sees it every day at her high school — the hyper-focus on designer labels, the must-have trendy cell phones, the classmates driving SUVs.

You could say it's just teens being teens. But new polls show that the obsession with material things is growing — and that being rich is more important to today's young people than in the past.

UCLA's annual survey of college freshman, released last Friday, found that nearly three-quarters of those surveyed in 2006 thought it was essential or very important to be "very well-off financially." That compares with 62.5 percent who said the same in 1980 and 42 percent in 1966, the first year the survey was done.

Another recent poll from the Pew Research Center found that about 80 percent of 18- to 25-year-olds in this country see getting rich as a top life goal for their generation.

"It bothers me because I would like to think I am the opposite," says Greenwood, a 16-year-old high school junior from Arlington Heights, a well-off suburb outside Chicago. She tries to keep her own spending in check under the watchful eye of her parents.

But even she sometimes finds it difficult to avoid the urge to fit in.

"Let's face it," she says. "Honestly, what teenage girl doesn't want to look cute and have the latest accessories?"

Young Americans' obsession with material things recently caused talk show host Oprah Winfrey to vent her frustrations, when asked why she chose to build a school in South Africa instead of this country.

"If you ask the kids what they want or need, they will say an iPod or some sneakers," Winfrey told Newsweek, referring to visits with students in inner-city schools. "In South Africa, they don't ask for money or toys. They ask for uniforms so they can go to school."

Indeed, researchers say materialism is an obsession that cuts across socio-economic lines for American youth.

"Our kids have absorbed the cultural values of more, easy, fast and fun," says David Walsh, a psychologist who heads the National Institute on Media and the Family in Minneapolis. He's also author of the new book, "NO: Why Kids — of All Ages — Need to Hear It and Ways Parents Can Say It."

As his book's title suggests, he believes parents have played an integral role in encouraging their children's materialism. His research found that, when adjusted for inflation, parents are spending 500 percent more money on kids today than just one generation earlier.

"A lot of parents have developed an allergic reaction to their kids being unhappy," he says.
