LONDON (Reuters) - U.S. pop superstar Madonna, one of music's richest performers, has attacked her fellow Americans for being obsessed with the "wrong values" such as getting rich and looking good.

Madonna told the Radio Times that Americans had opportunities people in other countries did not have but got caught up in superficial dreams.

"We as Americans are completely obsessed and wrapped up in a lot of the wrong values -- looking good, having cash in the bank, being perceived as rich, famous and successful or just being famous," Madonna told the television listings magazine.

"It's the most superficial part of the American dream and who would know better than me? The only thing that's going to bring you happiness is love and how you treat your fellow man and having compassion for one another." [...]
