What is the speaker's claim for the new American dream?

Incomplete question. However, I inferred you are referring to a speaker on the TED Show found here (https://www.ted.com/talks/courtney_e_martin_the_new_american_dream)

"The biggest danger is not failing to achieve the American Dream," she goes further to say "The biggest danger is achieving a dream that you don't actually believe in."

Explanation:

We noticed are appeal to parents concerning the new American Dream they have for their children. She warns about the danger of failing to achieve this "new American dream" by the words "The biggest danger is achieving a dream that you don't actually believe in."
